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).
It’s a tough call. The good news is that whatever you decide, it will feel like the right thing after you’ve done it. You’ll almost certainly say to yourself, “I’m so glad we saw both islands” or “I’m so glad we had 6 full days on Santorini.” In deciding I would ask whether a return trip to Greece is likely or possible in the next couple of years. If so, then spend your 6 days on Santorini and explore that island, then return to Crete at some time in the future for a deserving 7 to 10 days. But if this is a one-time deal for the foreseeable future then do 3 days on Santorini and 3 days in Crete. (Whatever you decide don’t do a day trip to the other island as it’s not worth the time and effort.)
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.
For the full throttle, utterly extravagant Las Vegas experience, it has to be the Strip. You’ll stay in a grown-up wonderland, in opulent, palatial surroundings, and there is nowhere else on earth with nightlife and entertainment like this. Plus, when it gets too much, you can simply retreat to your suite within a few minutes. If you’d like to be close to the action, but without the full force of the Strip’s frenetic nature, stay East or West of the Strip. Here, you’ll find some smaller boutique and budget hotels, and you’re still in easy reach of all the main attractions.
