I recommend the Park MGM for people visiting Vegas on a budget, watching a concert or hockey game at T-Mobile Arena, or want a centrally located hotel on a budget. This is also a good option for guys trips, girls trips, bachelor/bachelorette parties, and quick weekend trips.
I highly recommend Aria for most people visiting Vegas. It is a luxury hotel and the cost does reflect it relative to other properties, so if you’re on a strict budget, you may not find Aria in your sweet spot. But because of it’s amazing food options, lively casino, amazing central location, and overall hip vibe, Aria is one of my top recommendations.
