I've only been to a Royal Caribbean cruise, but I didn't feel the need to put my laptop in the safe, I just left it out of sight. We did put the passports and wallets in the safe. One night I returned to my cabin a bit tipsy, and then I realized I had lost my scarf. So I went out again to find it. Someone had left it adorning the miniature of the ship 🤣 It was really funny, I didn't think I would find it.
