Absolutely amazing. I wanted to see O by Cirque, but heard this is better (and cheaper, though not cheap). I decided to go with Le Reve and used the code DSAVE30 over the phone to save $30. We got the regular seats, which were awesome! Not the cheapest or most expensive. The splash zone is pretty low and you really should get the level up for seats.
The seats in the arena are very comfy and plush! We didn't partake in the concessions but there were a lot available. There is a nice store with Le Reve gear outside the entrance, and I bought a few things there.
The show started and I was awestruck the ENTIRE time (unlike in LOVE by Cirque, which I also saw). These performers are TRUE ATHLETES and absolutely fabulous in their skills. The stage turns from stage to pool to pool and stage seamlessly. The music goes perfectly with the show. Some of the tricks they did were unbelievable. I won't give them away here, but they took my breath away.
I got my fill of Vegas and don't care about coming back to see anything but shows... and this one would be #1 on my list to see again, despite the cost. I can't wait to come back so I can see it again. JUST GO. You won't regret it.
