So I also stayed here for 3 nights, 4 days. The rooms were clean roomy and good smelling and since my friends spoke spanish they were able to get a few extra towels, pillows, ice bucket, toiletries from the maids (we tipped of course).
The place was crowded, yet the staff was almost anticipating every single question you had for them, well except a snotty, blondish filipina looking cocktail waitress who totally ignored me a few times after I asked her to please grab me some beers on a quiet 5am morning while I play some slots.
I still give this place 4 stars even though I totally showed them a lot of love(wasted money) on their slots.
If you want to be on the plus side when gambling on slots. Or wanna play roulette with only a 5 dollar minimum you HAVE TO GO TO THE OLD CASINOS in DOWNTOWN(6 miles north on I-15, exit downtown sign to exit at casino city center. People have mentioned this over and over but not a lot of tourist when they get to Vegas ever make it off the strip. That's where my friends and I spent and Won the only money we gambled.
The self parking at MGM is a nightmare if you don't take the basement escalator from the main lobby. The "roll away" bed is very comfortable. The open bottle/open container while on the strip outside is LEGAL. So I ended up walking the strip or on the casino floors with plenty whole bottles of Moet champagne in hand and the cops or casino secuirty could care less.
Tabu nightclub and Studio 54 nightclub both located at MGM are free to get into as long as you have your MGM room key, have an I.D. +21 and at least get in from 10p-12p. Once you have your stamp you can go in and out. (Easier to get free liquor on the casino floor) these clubs have standard very pricey drinks.
