Hydra is great but it does take a bit of time and effort to get to from the Cyclades. You’ll need to ferry to Athens, then might have to overnight there, then ferry to Hydra. Whereas Naxos, Paros, Milos, Folegandros, etc. would all be one direct ferry from Santorini or Mykonos. If you do go to Hydra then Leto Hotel is a great choice close to the port and shops and restaurants.
Went to Fiji for my honeymoon and i don’t think that trip can be topped. We wanted seclusion, privacy and romance and thats what we got. Our bure was 20 feet from the beach where we could relax and maybe see 1 or two people all day. It was incredible. The resort was called Matangi island resort. Great staff, great food…. It’s as close to perfect as you can get.
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.
