I am a scuba diving and I am booked on the Voyager of the seas for May 19. I am planning to do some scuba diving in some of the ports and way wondering if I should bring my own Mask, Fins, and Snorkel.
I could fit them in my suit case so space is not a problem.
If it's snorkel equipement only, I'd take it if you don't mind packing it AND if you don't mind carrying around the port. When you're done snorkeling, you may not go directly back to the ship. Just make sure you have a back pack or some other bag that you're comfortable with.
If it's scuba diving, I wouldn't bother taking your fins since you'll need the other equipment from them anyway.
