For $59 a night, the Excalibur is an excellent deal. The hotel is less than ten years old, so it's still in pretty good shape. It's in a great location, beside the Luxor, MGM Grand, and New York, New York.
The hotel is pretty huge, and lots of families stay here, so be forewarned that there will be lots of kids running around. The pool area is always pretty full.
The rooms were large (two queen-sized beds), and we had a nice view of the Strip.
If you don't mind kids, this is a great bargain.
