Good afternoon. I am booked for a trip to mid-town Manhattan late September using Priceline. Using the hotel confirmation number through Marriott.com, I am able to see my reservation. Both the Marriott and Priceline confirmation pages display the same information as to dates, room type, and number of travelers. However, on the Marriott confirmation page I see the following under "Billing Information" Billing Information Your reservation is guaranteed to your: MasterCard ************2331 I did not use a MasterCard to book this trip. When I called Priceline to inquire, they stated that since I paid Priceline for the hotel, Priceline then pays the hotel with the MasterCard ending in 2331. Is this typical? I just want to make sure that when I check in I am not turned away for not having in hand a MasterCard ending in 2331. Thank you in advance for your help!
