Been here a few times & every time was a gooood time.
I like being outside more than I do inside, but that's just me. Being by the pool is nice & there are heat lamps outside, so you're not cold. Plus, there's just a bunch of people everywhere that its hard to not be.
Inside is just as fun... a bit more crowded though. I've always ran into a friend when there - which is crazy for being how large it is.
Great vibe & energy from the crowd.
