Great but long - It was great and everything was done very well for the money. However I had no clue what to expect and there is a lot. What to expect-first you get picked up at a bus stop but not the city bus service. Think of it as a bus pickup but everyone is going to the same place. You wait in line for your tickets but don’t worry everyone gets on the boat. When you get on the boat you start in the bottom standing with now windows. Don’t worry you won’t be there long. You are filtered upstairs to a beautiful seating area for an over 3.5 hour boat ride. Once you get to Santorini you will be assigned a bus number where you spend your day. The tour guide will give you history while you make your way to the first stop. You can get out for over an hour for pictures and shopping or eating. Our tour guide said don’t buy souvenirs here unless you see something same with eating. It is more expensive than the next and last stop. They then take you to the capital where you can get lunch and shop for a couple hours. This seemed more than enough time in the heat. You have a very strict schedule so the boat doesn’t leave but that was expected. At this point you do it all over to get home. Trip was great and as expected but note it is a 15 hour day.

Not really enough time on the ground to see or enjoy Santorini. - Nothing wrong with the tour operator, but 4 hours in Santorini on the ground is not enough to do much especially since you have to eat lunch there and service is not always fast.

Could be bette! - No connection with Viator whatsoever. The worst part was at the end- we did not have the number of the bus to take us back to our hotel in Chania. Other groups had numbers of the busses on cards, given by the driver in the morning. It was already dark, the busses were leaving and we were stressed running from driver to driver to find ours. I think for the money we spent we had to get better care!

Disappointing - This trip was a waste of time and very disappointing. Santorini is overrated and very very crowded. There was no time to explore anything. Most of this trip consisted of traveling in the bus and on the ferry. We spent 1.5 hours in Oia which is nowhere near enough to get the feel of it. Half an hour in Thera was laughable. We paid for the optional trip to the volcano which was short and not worth it. Visit Chania instead.
