Those are 3 great islands. Corfu is much more green than Crete and Santorini and does have a different feel (more Italian but it’s no where near Turkey). The trouble with doing all 3 is that Corfu is on the opposite side of Greece from Crete and Santorini so you’d need to fly via Athens. It’s better for most people to visit another Cycladic island (Naxos, Paros, Milos, Folegandros) instead of splitting up their trip between the two sides of the country.
Christened the Garden Island, Kauai’s splendor extends from its vermillion Waimea Canyon, plunging down 3,600 feet, to its rugged Napali Cliffs, stretching up 4,000 feet. Often dotted with dozing monk seals, Kauai’s Poipu Beach has appeared on Dr. Beach’s esteemed list of America’s Best Beaches. Rivers, rainforests and waterfalls garnish the interior; don’t miss a photo op of Wailua Falls, famously featured in the opening credits of Fantasy Island, which aired from 1977 to 1984.
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.
I am so disappointed that I was not there longer but I realize we could not do everything, if we were there for extra days. I think I will stay at a different resort on my next visit. We really enjoyed Vegas overall. I ate at various places to be sure I wasn't eating the same things. It was easy to access Uber/Lyft. This was the most appropriate method of traveling, just in case we partied too hard. We enjoyed the live music. There was a group performing R&B and then a gentleman mixing Reggae music. Everyone seemed to be enjoying it.
Airlines have substantial fixed and operating costs to establish and maintain air services: labor, fuel, airplanes, engines, spares and parts, IT services and networks, airport equipment, airport handling services, booking commissions, advertising, catering, training, aviation insurance and other costs. Thus all but a small percentage of the income from ticket sales is paid out to a wide variety of external providers or internal cost centers.
