I am going on the Valor Oct 26 WC cruise and signed up for the Tabyana Beach break excursion. I figured we would go early so I picked the first time which is 11:15. However, after booking I noticed it says that the ship doesn't even dock until 12:00. Do I need to switch the time myself or is something wrong with the times themselves? I am a little confused about this but want to make sure I am on that first bus to the beach.

you will be one of the first ones off dont worry. and Tabyana is great if you like to snorkal the reef is only about fifty feet from the beach. the ship will dock and the buses run about every 20-30 min. or when they get full. the beach is just wonderfull.  On the return they run busses every 10 30 min they will make sure you get there and get back in time.  

 Can you rent the snorkeling equipment at the beach or do I have to get it from the ship? I wanted to go there so I could snorkel while my partner relaxes on the beach. He doesn't get in water over his head so this seemed like the perfect beach for us. Thank you for your help.

 I didn't noticed any snorkeling rental equipment at Tabayana beach, I brought my own. But maybe I'm wrong, anyway I will advice to buy your own, the rentals I don't know how clean they are, one time I took a snorkel excursion in Belize and they didn't clean the tube mouth-piece at all.
