BlueBonnet...Bally's has, on average some of the largest rooms of any LV hotel. I've stayed there 5-6 times and find the desk staff to be great. Depending on how busy they are that week, or how many other conventions are in town, you could get an upgraded Jacuzzi room. Unlike other hotels, the hotel & casino are run separately, so you won't find a lot of high-rollers getting the good rooms.
For leisure time..if you will have a car, get out to Red Rock Canyon or drive up to Mount Charleston. Actually, I think you can do a day rental right from the lobby in Bally's
(Budget I think). If you're a golfer, great courses there but all are expensive (even the public courses). It's an expensive ticket, but if Cirque de Soleil or their new show is playing, try to catch it. It'll blow you away!! Siegfried & Roy show is OK, though getting old for me; I've taken clients there too many times. Good restaurants in MGM, and by all means go to check out Mandalay Bay at the end of the strip (left out of Bally's).
I could go on forever, but that's a start.
