LoveBora is completely correct. Whatever whomever decides you can't bring on board won't be allowed.
I took some visiting relatives out on a dinner-casino cruise here in FLL. One had a tiny (like 1 inch) Swiss Army Knife on her key ring. They confiscated it.
The kicker is, once on the boat we were served metal steaknives with our meal!
