Just got back at the end of September.
A few notables.
I do not like staying on the Las Vegas Hilton/Sahara/Stratosphere end of the strip.
There is more action (ie. more hotels) between the MGM/NY NY side.
Loved the Mirage buffet...try to go during late breakfast/early lunch (11:00 a.m.) to catch the changeover food (cooked to order pasta bar.....YUMMMY

)
Went to OPM at Ceasar's Forum Shops. The club plays hip hop and remixes. I enjoyed it. Ate at the Voodoo Cafe and Lounge at the Rio. Its on the 51st Floor. The food was pricey, but the decor was cool, plus there is a view of LV and an outdoor patio. 5th
I think they are opening a Planet Hollywood Hotel near the strip in 2006, plus Mariott and Hilton are building hi-rise time shares within walking distance from the strip.
All in all, Vegas is a perennial (sp?) favorite of mine. I could go every 6 months.
