Transport between the three islands relies on local ferries and these are unsophisticated ‘landing-craft’ style boats that do little more than ferry passengers and vehicles in Spartan comfort, but they are very functional and vital to the inter-island communication. There is plenty of on the ground support excursions and infrastructure and the islands are well-used to tourism; the only exception is that travellers will need to use a bit of independence in getting between the islands.
You seem to have your heart set on Zakynthos but I have to say it’s not a good use of time for a sort-of overrated payoff. Your time is much better spent (in my opinion) seeing another Greek island in the cyclades (maybe taking a ferry to Naxos or Paros sitting outside on the deck drinking a bottle of wine) rather than taking a bus and connecting flights. Zakynthos and Santorini/Mykonos are on opposite sides of the country and the only way from one to the other is by flying (or some combination of bus and ferry). So, my recommendation is to consider spending those Zakynthos days in Naxos, Paros, Milos, or some other Cycladic island.
To sum up: a lot depends on your own stamina because island hopping means packing and unpacking, getting on and off buses and ferries. Limit your choice of islands to perhaps one or two less than you think you can manage. Maximise transport links to avoid backtracking or port-transferring and since you are traveling high season be aware that you will usually need bookings ahead at most places. It is possible to turn up on an island and not find a place to stay or have to make do with a third-rate option.
Argostoli is the capital on the mid-west flank of the island and is not really a destination itself, that moniker falling to the contiguous beach scene running from Lourdata south eastward to Skala. While development might have caught up here by now, it should still be a pleasant beach scene and focus for a relaxing stay. The Melissani Cave on the east coast is a must attraction and while it can be visited on a day excursion from anywhere on Kefallonia the two villages or Agia Efthymia and Poros are low-key ‘resorts’ pulling in a regular crowd of travellers and may warrant a look-in. The port of Pesada (just west of Lourdata) is the home of the local ferry to Zakynthos (Zante).

Crete, Santorini, and Naxos look quite doable within the 12-day block, but Crete’s beaches are scattered throughout a very LARGE island, Santorini really only has Kamari and Perissá (and some southern coast bays) and Naxos does have nice places to swim. If you choose only to visit those three islands in your relatively short time, you will do well.
Panama is an underrated destination in Central America, including the San Blas Islands. This is a popular spot for sailing and boat tours, though there are also some resorts in case you’re looking for a more luxurious stay. Generally, the islands are quite rustic and make for a great off-the-grid island getaway. There are tons of beautiful spots for good sailing, diving, and snorkeling.
Located in southern Thailand, this semi-off-the-map island is one of my favorites and the month I spent here remains one of my most fond memories. Here on Ko Lipe, the super-friendly locals bring in the daily catch for amazing seafood, as the island’s water is teeming with life. Accommodation is still basic, and most places turn off the electricity around midnight.

There are 700 islands that make up the Bahamas, which extend 760 miles from the coast of Florida nearly all the way to Haiti. Of course, the majority of those islands are uninhabited, but those who want to visit still have practically an overwhelming number of destinations to choose from. If you’re hoping to truly get away from it all, don’t head to the most popular isles like Grand Bahama, consider one of these instead, then explore some of the country’s other top attractions.
Bermuda is recognized as one of the most elegant of the Caribbean islands, and also on the formal side. It has a strong British influence, and you can still find many places that serve traditional afternoon tea. Cricket matches are also easy to find. Bermuda is also a great destination for golfers, as the island has many world class courses. This island is extremely convenient to reach from the Eastern U.S. Flights from New York to Bermuda are only two hours.
I’m a little worried I’ll get bored in Milos. My husband likes to stay in one place, but I like exploring. We would have split our time more evenly but we want to stay on the caldera and it’s just too expensive to stay any longer than two or three nights. Alternatively, we could stay in Santorini for longer but move to a cheaper hotel. Perhaps Santorini 6 nights and Milos 6 nights?
Unlike its luxurious Caribbean neighbors, here you’ll only find more budget-friendly hotels and guesthouses. Everything needs to come by ship or airplane, so it’s not super cheap. However, since no non-natives can own property there is no influx of overdevelopment, keeping the island simple but beautiful. For a more rustic, non-touristy getaway, this might be the island for you!
Kate Hudson, Goldie Hawn and Amy Schumer were among the first guests at Four Seasons Resort Oahu at Ko Olina, a 642-acre that opened in May 2016 on the island’s west coast 17 miles from Honolulu. Closer to the action of Waikiki, the Surfjack Hotel opened in May with a dose of vintage 1960s Hawaii, down to its painted murals and birds of paradise wallpaper by local artists that are just begging to be Instagramed. Pacific Beach Hotel re-emerges in the fall as Alohilani Resort Waikiki Beach, whose $115 million upgrades include two new restaurants by celebrity chef Masaharu Morimoto. 

Ferries between Naxos and Milos don’t start until June 7th (one each way, every day after that). Ferries between Santorini and Milos start April 28th and there is one every day in each direction. And there are always ferries between Naxos and Santorini. So if the dates work I would fly to Santorini (the longest leg) then ferry to Milos then Naxos and back to Athens. But if you need to travel between Naxos and Milos before the 7th then ferry Athens to Milos to Santorini to Naxos and back to Athens.
Barbados is a vibrant island with a great nightlight. Bridgetown is one of the nightlife capitals of the area, so if you’re looking to stay up until the wee hours then this might be the island for you! Like Bermuda, you’ll find amazing beaches and caving here. You’ll also find some world-class surfing. The food here is amazing, and you’ll be able to enjoy expensive, delicious meals alongside cheap local food.
Remote and unspoiled Crooked Island has little in the way of tourist facilities, but it does boast gorgeous beaches, bat caves and flamingos, and also serves as a turtle nesting spot. One of the four islands that form an atoll hugging the striking shallow waters of the Bight of Acklins, it hasn’t much changed since Columbus sailed down the leeward side through the narrow Crooked Island Passage. There are miles of untouched, white powdery sands, coral gardens, limestone caves and cliffs, remnants of slave and cotton plantations, ancient churches, fortifications and mangrove-lined waterways.
