We stayed here with our 13yo during his spring break, last week.  The hotel is beautiful but very crowded.  I really liked our room which over looked the fountains.  They are amazing and especially at night, worth the extra amount we spent to get that view.  The bed was very comfortable.  We ate at the buffet for 2 breakfasts and one late lunch/dinner.  It was very good and the staff was friendly and efficient.  I personally didn't care for Vegas but not because of the hotel.  Not impressed with the pool(s) or the paid wi-fi.  I complained, nicely about it, couldn't download a thing or get email (!) and they refunded 2 days out 3, which was unexpected but very much appreciated.  They also let me use their computer to check-in for our flight and print boarding passes for free.  It is in the center of the Strip and the airport is only 10-15 minutes away, so use a cab and not one of those shuttles.  The cab was about 1/2 price in comparison.  We did use the monorail and the 2-day bus pass, which were both good but the bus is probably a better deal in the long run.
