Thought I'd just chime in about prescription snorkel/scuba masks. RCCL SoS does not have a dive shop like the Golden did, so we won't be able to rent prescription scuba masks. I searched the internet and found a few different places to order prescription scuba masks for under $70. When I rented them on the Golden they were $35 a week! So in two cruises they'll paid for themselves. If you are nearsighted and don't wear contacts prescription masks are the way to go. If you're interested in them just google prescription scuba masks or check ebay.
