When we were in Marriott Munich, the front office staff forgot to give me any information about their lounge (there were a lot of guests checking-in that time, so I asked for it and coupons were given. I think you have to ask=) Marriott staff are very friendly and helpful=)

Room upgrade for platinum is not something that you will always get. We got a corner room upgrade at Marriott Munich and a junior suite upgrade at JW Marriott KL. Again, you have to ask for it, in a nice and friendly way=)

You should get welcome gift whenever you check-in at Marriott hotels. Again, ask for it=) The staff of JW Marriott KL forgot to offer me the welcome gift, they were very helpful and friendly during the check-in process plus they are arranging something special for my girlfriend's birthday, so I didn't utilize the Platinum guaranteed benefits, but instead, I just got back to them and ask for the welcome gift.

Don't be shy to ask for some information. As long as you ask with a smile, they would help you with a smile=)
