Oh no! Yelp just informed me I didn't write a review for The Signature yet!
We love the Signature. We've stayed there twice in the last few years and would stay there again in a heartbeat.
Pros:
Beautiful rooms with comfy beds and wonderful soaking tubs. There's even a mini-kitchen complete with cooking utensils and real glasses.
The atmosphere is unbeatable; quiet & relaxed with a friendly and very helpful staff.
It's a non-gambling, non-smoking facility, but it's connected to the MGM by an indoor tunnel/walkway. It's about a 10 minute walk, but you get access to the fun/trendy MGM pools as well as the swankier Signature pools.
Valet parking/private entrances. You don't get into the Signature unless you're a guest or event attendee. There's gates at the entrances and a key-card entrance to the tunnel/walkway.
Cons:
It's a little pricey, but a much better deal than other nice hotels on the strip, including the Wynn which is similarly appointed but about $100-$150 more per night.
It IS a 10 minute walk to the casino. Which is OK during the day, but a little hazardous at 2am when you're totally smashed and just want to go to bed (or at noon when you're totally smashed on your way back from the pool (sangria served poolside) and you fall and skin your knee).
Not much in the way of food here, a nice pizza/sandwich place by the pool and a snack bar, but most everything else is out in MGM.
