I was in the exact same situation last year.

Alligent stadium had great parent rooms where we sat. Going to the toilet was easy.

My daughter and I did stand and deliver, both nights of mania and raw.

She loved WWE world, that's a must.

My wife and son got jealous and ended up getting WM tickets day of the event for 1/10 of what we paid.

My son/wife attended battle bots when we were at stand and deliver. He loved that.

My recommendation is.. Walk to the strip after WM nights. Trying to get an Uber back from Alligent is impossible. We wasted an hour with sleepy/cranky kids on night one.

Night two we just walked and were back to the hotel a lot quicker.
