having not stayed in many Suites in vegas with the exception of the Rio I'd like to now which suites are others favorites. Now keep in mind I'm talking about ones you've actually stayed in not just on TV or on line.
Let me first say I'm a low roller (no actually I'm cheap) that being said I stayed at the Jockey Club in a suite that I thought was awesome. This was a real 2 room suite with a full kitchen. Full size fridge and oven, dining room table and chairs. Our view was the Bellagio Fountains so for about a 100 per night I thought it was great.
Definitely the Spa Suites at Golden Nugget. Two story 1400 sq ft with spiral staircase, spa, steam showers, dining area, wet bar, living room, and upstairs bedroom. It was one of the best deals around for $59 to $99 a night the last few years. Sadly, they fixed the bug on their website and the cheap prices are no longer available.
There are plenty of suites I have NOT been in...but my favortie one was the penthouse at the Mirage. They upgraded me from my purchase of a regular suite....the penthouse is as big as my house with an awesome view...full formal dining room....and my favorite part was the little TV that popped up at the foot of the bed with the press of a button.
My wife got what must have been a marketing mistake from Aria providing us with RFB and a sky suite. It was the finest suite we've ever stayed in and the view was stunning. Given our mid-level rate of play- the offer has not been repeated (darn).
My favorite was a strip-view corner suite in the fantasy tower at the Palms. I had booked a regular room on sale at $56/night and was given a free upgrade when I checked in.
