This review is for the Ballroom/Conference centers at the Four Seasons.
I was present for the Nevada AAP conference over a Fri/Sat. Conference center was beautiful, clean, and classy. They had a great tea selection and there were silver pitchers of water and clean glasses at every table. The service was very very good - at every break, plates/dirty cups were removed and waters in the conference room was refilled. Food was superb, fresh, and well done. The provided continental breakfast was nice - very good fruit and pastries. The lunch had a good selection of veggies/salad, pasta, beef, salmon and chicken - all of which was of high quality esp for buffet style.
Valet was a little slow, but otherwise service was great! There is no "self parking" unless you use the Mandalay Bay parking.
Only complaint is that the conference rooms were FREEZING! I guess that was their way of making sure we didn't nap during the lectures, haha.
