The Plaza is one of the older hotels left standing in Las Vegas, and as such, it's not exactly glamorous or high-end. It's also pretty large, so there's always one part of it under renovation, and another part that desperately needs renovation. In order to keep the money rolling in, particularly in the off-season, the Plaza offers group discount rates and sells off blocks of rooms to the timeshare people. These are always the very worst rooms, either in desperate need of renovation, or right next to construction areas, elevators, laundry rooms, and ice machines, because these rooms suck and aren't worth as much money. The vast majority of the bad reviews about the Plaza on Travelocity and similar sites come from people who stayed in these discount rooms, either as part of a budget tour group for old people, or as a free timeshare giveaway. The Plaza also saves its best rooms for people who book direct, so if you book through Travelocity or whatever you'll always get a worse room for the same price than if you'd gone to the Plaza's site.
The Plaza is not glamorous, but it's a decent enough middle class hotel right at the foot of Fremont Street. Fremont Street itself is really great, tons of free live music, little touristy shops, restaurants, and bars, other old-Vegas casinos, and busker weirdness to keep it interesting, while having a strong enough police presence that you're mostly safe ON FREMONT STREET. Wander a block or two off Fremont Street in any direction and you're in a 3rd world ghetto. This is true of most of Las Vegas though. The Plaza is definitely nicer and classier than, say, Circus Circus, UNLESS you get one of those discount block rooms.
I've been to Vegas a number of times, and I've come to prefer the Downtown area over the Strip due to the lively atmosphere and lower prices. Seems like the walking distances are shorter too. Still, the Strip has more luxurious free attractions like the fountain show and the art installations at Bellagio; you won't get that type of stuff Downtown. I just get an Uber over to the Strip for all that stuff now.
As such, the Plaza is a pretty good place for these fags to have their shitty event. The Plaza is probably too good for them tbh.
