Yes, they have in room safes. However, do not expect a Plat suite upgrade. (Read the thread & you will see what I mean).

I had a fridge for my last stay, and the FR DESK made a big deal of waiving the fee. My advice? Wait till check in, remind the GOLD/PLAT desk rep it was on your request list and ask them to comp it.

Also, make sure you pick up the biz. cards in the lounge. They are handy for contacts for such requests.
