We are taking a Mexican Riviera cruise next week and I hate to go "naked". What can I reasonable expect to be able to take. Knife? Multitool? PSK? FAK? I suppose I should will contact the cruise line, but any thoughts or experience on this? Thank you in advance.

I am soo used to EDCing a knife, multitool, several lights, a whistle, BSA Hotspark that if I cant I will feel totally unprepared...
