We signed up for the Royal Swim through Dolphin Discovery in Cozumel. The excursion is at 3:30 pm. They go by Cozumel time, not ship time. Ship time at the start of the excursion would then be 4:30 pm. Our ship sails away at 7:00pm. The excursion is said to be an hour and video/photos are ready for viewing immediately. If we have to be back on the ship by 6:30, do you think we will make it? For those of you who have done this excursion, how close will we be cutting it? How long is the taxi ride to Chankanaab? Are taxis ready to go or hard to find? Thanks!
