I visited the Wynn Theater to see the Le Reve show while my family was in town and I was definitely impressed! It's a gorgeous theater that is clean and spacious. Like most of the reviews mention, the theater is laid out in a circle so there is truly not a bad seat in the house! Getting to our seats was a painless process, although I wish there would've been another entrance we could've went through as our seats were on the other side of the theater.
I docked a star for the annoying light flashing that one of the ushers had going on during the middle of the show. I understand they don't want people taking videos, but one of the ushers literally sat and clicked her flashlight on and off for about 5 minutes trying to get the attention of one of the guests to put their phone away. It was definitely distracting and probably could have been handled in a better manner.
As far as Le Reve goes, it's a top-notch performance that is a must see if you're looking for a fabulous acrobatic type of show. I've seen many of the cirque shows on the strip, but the inclusion of all the water work this show has sets it far apart! This is definitely a show I would return to see again and again!
