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.
Every imaginable shade of blue manifests in the lagoon of Bora Bora, aka, the Jewel of the South Seas. Coral motus ring the main island like a sandy sash, and beneath the surface, dolphins, rays, sharks, turtles and colorful fish throng. Presiding over it all is the moss-green volcanic peak of Mount Otemanu, where god descended to the island on a rainbow, according to local lore. Timeless grass-skirted dancers and exotic overwater bungalows round out the sublime scene.
We’re on a budget (think €50 per person per day) and would like to go someplace warm and sunny where there’s also a combination of culture and nature. So we can explore in the mornings and relax at the beach in the afternoon. Preferably a sandy beach. We don’t need a lot of nightlife but it would be nice if not the whole island is closing down already. Do you have a suggestion?
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.
Where to stay in Zante: Porto Zante, eight villas with five-star facilities, set above a pristine bay of finely raked sand, is kitted out for kids of all ages: there's a playground, mini-golf, and every water-sport under the sun. The sociable Peligoni Club is especially good for toddlers and teens: the crèche is run by qualified nannies and over-13s have their own bar, serving milkshakes and mocktails. Zante Maris Suites, as well as the new Olea All Suite Hotel just next door, are both squarely aimed at adults, with a haute hippie vibe. Kids over 12 are welcome.
The almighty church has kept nightlife in check. If you must see and be seen, head to quietly glamorous Astivi or Stoa bar, on miniature Agia Lesvias square, in Hora. Beach life is generally languid and low-key; Psili Ammos and Livadi Geranou are our favourite hideouts. Dinner reservations are essential at Benetos, for Med-Asian fusion on an organic farm, and Lambi for grilled fish on a purple pebble beach.
