I have stayed in many hotels and casinos over the years in Las Vegas and this time I really wanted to push the boat out. The Four Seasons did not disappoint. The new rooms are beautiful and fitted out to a very high standard and refurbishment work appeared to be ongoing in communal areas and the pool and spa. These public areas should be good when finished, but it was a shame they were closed during our stay. That is why I have not reviewed the Spa. It is woth pointing out that breakfast is a little expensive, somit try to get an inclusive rate if possible . We did have breakfast in our room on Christmas day, and the food and service were excellent. As part of the Mandalay Bay, it is worth visiting The Mix at the top of The Hotel, and the spa in Mandalay Bay is amazing. If you want a fantastic stay in a non casino hotel with a great personal service and a really comfortable room, the Four Seasons is the place for you.
