We had driven all the way from Indiana to Philadelphia to a funeral of 103-year-old cousin which evidently is irrelevant but when we pulled in, we found the place and we were gonna let people out to go check in. We were bombarded by German and said I’ll give you $20 for one hour or you got five minutes to go check in can’t check in in five minutes I think that the hotel staff or property owner needs to get a better grip on the parking for there, the prices are very reasonable but the rudeness of someone coming up to you or to your car saying that we were State was very disrespectful
