Grand Garden is easily repurposed.I guess the question comes down to can Vegas support that many full-size arenas? Between T-Mobile, Thomas & Mack, this place, and (depending on how you define full-size) MGM Grand Garden Arena, that's 4.
Honestly, I'm kinda surprised MGM Grand is still in use. It's never seen a major renovation (not even upgrading the ad boards near the ceiling to LED ribbon boards) and been largely displaced by T-Mobile in terms of the place where MGM Resorts schedules their main bookings.
It’s Vegas. Everything is easily modified or repurposed (T-Mobile maybe a little less so). They do entertainment. Casino bigwigs will probably tell you there’s not enough arenas.
