I noticed OP also says sand, but the replies seem to be about shells. Does anyone know if it's prohibited to take sand? I had been considering a cute FE gift I found on ETSY which is a keychain with a mickey charm and a tiny bottle (about a thimbleful) that you can fill with sand to remind you of paradise. But is that going to get cruisers in trouble (or offend people who are concerned for the beach environment)? I frankly think I tracked more sand on board just from what fell into my diaper bag from putting away our things at the end of the day.
