We are currently on the 7 day Greek Isles Cruise on the Dream and took this excursion yesterday in Santorini. The experience was so horrible that I felt compelled to share what happened so hopefully we can save other families from having to endure what we did. This 7.5 hour port adventure is described as “a DAY of sailing and swimming.” The port adventure began at 8 am. We were taken on a 45-60 min bus ride to Oia for an hour of shopping and photo opportunities. Then we took another 45-60 min bus ride back to where we started to finally board the catamaran. It was 12:30 pm by this point and since we were already 4.5 hours into the port adventure before we saw the boat, we knew we had made a big mistake. We were supposed to take the catamaran to three different locations to swim but they said we ran out of time and only went to two instead. We were only given 10-15 minutes of swimming time per location. Based on the description, we were expecting a day of swimming but only swam for a total of 25 min at most. The catamaran brought us back to shore and despite being dropped off at this location in the morning and being able to see the dream, we were told we had to reboard the bus and drive back another 45 minutes to Fira. There the guide dropped us off on the side of the road with no directions provided on where to go. Eventually we figured out how to get to the cable car but the wait time to get back down to the port was 1.5-2 hours. We decided to take the stairs because the Disney crew told us that morning it was a 15-20 min walk. It was much longer because it was literally a steep incline down a mountain and the stairs were slippery and covered with donkey crap. Both my sons fell and we saw an elderly man fall. Later that night my son saw a friend from this kids club and his leg was cut open from falling on the stairs. By the time we got back to the ship, the port adventure took a total of ten hours and again, only 25 minutes of swimming. I strongly advise anyone booked or considering this port adventure to cancel or make other plans. I cannot express what a miserable day this was.
