Hotel recommendations for out-of-town guests?

Philadelphia has a number of hotels, especially in the Center City area. It really boils down to how much your friends want to spend per night, and if they prefer to be close to tourist attractions or not.

Some great options include the Courtyard Philadelphia Downtown, the Hotel Palomar, the Hyatt Regency at Penn's Landing (particularly nice in the summer when guests can walk to attractions at Penn's Landing or cross over a little bridge right into Old City), the Loews, and The Penns View.
