I checked into Hunt Valley Marriott today and I noticed they didn't swipe my credit card. I will be sure to examine the bill in the morning and do a manual out tomorrow to make sure that all goes smoothly with the cc. I have 2 cc's in my profile - one is an Amex and if they bill it to that one (I reserved it on my MR visa), I wont' get promo points credit.
I'm going to go delete the Amex from my profile now.
