I am staying two nights each at PH Milan and PH Zurich. I used my GP Points for these stays. I just got a free upgrade certificate for being a diamond member. Technically, I can't use the certificate because I didn't pay for these stays. Do they bend the rules sometimes when there's suite availability?

Also, I would be driving my new BMW to the hotel and from what I heard parking is very expensive at Milan. Does anybody know cheap and reliable garage near the hotel? Does PH Zurich charge for valet parking? I forgot where I got the information, but I thought it was free.
