I toss everything (except fins, too bulky) into a duffel and bring it with me.I would NEVER leave ANTHING of value (especially my $1000 dive kit) in a crew room.

KCM's no sweat.

Second the computer. Suunto ZOOP. $200. Works great, lasts long time. Bonus points if you wear it the whole trip. "I got your big watch right here!"

Enjoy!
