Have been to several concerts there. (Adam Lambert, Fifth Harmony.) The set up is nice, food is expensive-which is sort of to be expected anymore for something like this. The "line" (better described as writhing mass of desperate bodies) waiting to purchase your merchandise is always ...not really a line, and interminable. I think if you were disabled it would be very difficult to manage. I have some anxiety when pressed amongst masses of people and it's very wearing.
The sound system is good, but expect it to be loud. You might want to bring earplugs to tamp down the sound for comfort. The stage has two large displays next to it so you can see more clearly if you're not close. Which is nice. All in all as very nice concert venue. I much prefer it to the bigger venue at Mohegan Sun.
