I'm a cruise newbie that is feeling overwhelmed. I leave on Carnival Vista 4/29/18 and have a few last minute questions.
So I’m going to swim in stingray city in Grand Caymen, and with dolphins in Cozumel. Where do I put my stuff while we are all in the water? Is there a good waterproof bag that you recommend, or are there lockers at both places? Do I just bring off board my Carnival card (sail and sign card i think) and ID. i have 2 young kids without drivers licences, should I bring their passport or birth certificate off at the ports for their ID? Are the only required documents to board initially that I must bring are the boarding
