Maybe not super important but I can tell you to avoid the Delta hotel by Philadelphia airport, our room was terribly musty and I got really bad headaches. Lots of airline staff came here and they seemed to be well taken care of, everyone else, not so much. Fitness area and restaurant were good though! The staff at the desk couldn't have cared less about the musty ness but when I gave a negative review to Mariott they instantly apologized and said they wish I told them as they would have found me a new room...
