We have stayed at the Hilton Penn's Landing quite a few times over the past several years. We were initially very pleased with our experiences but are very disappointed this past year. We just stayed 4 nights over the Thanksgiving holiday. Once again, as in prior visits this current year, the room card entry system was not working. We have been warned to keep the cards away from our cell phones but found this did not matter. This most recent visit, we were assigned a room on the 19th floor and were provided 2 cards. Each time we returned to our room, neither of the cards worked. We would then be required to go back to the Registration Desk and wait in line with those registering to get new cards. On occasion, these failed to work and would require returning to the Registration Desk again. We were asked if we requested to have maintenance check our door lock (did not know it was our responsibility to ask) and were told by other staff this is a known problem and the locks will be replaced in the future. We will not be returning.
