The safes at WL aren't much bigger than those in the Values or Moderates. And lock with a key, not a key pad.
You could fit an iPad in there, but not one of the big Pro series. And not much else as the safes aren't very deep, may be 2 inches max. I could fit my 8" Fire HD tablet, my wallet, iPod and Bluetooth ear buds and that was about it.
Ditto - cash, passports (in case the TSA goes wild), a bit more. Worse, as the closets have no lights? We carry a little pen light so we can FIND the silly thing .
I'll put my car keys, some extra trip cash and any event tickets in the safe. I keep my bars of gold and bags of valuable coins, jewels and diamonds at home in a real safe. And a coffee can filled with cash buried in the yard.
