Hmmm I was born and raised in Las Vegas. I have not heard of any forums in particular because usually when we travel there, we go to just visit family like in any other normal town...just happens to be Vegas! LOL
If I had any recommendations though (we are not gamblers or drinkers---so it may be different than most people who travel to vegas....) I know I would definitely love to see one of the Cirque du Soleil shows there. I know there is a water one called "O" that I would love to see. It is at the Bellagio...beautiful hotel!!! Probably a little pricey though...
Also, we love looking around at the different themed hotels, New York, Paris, italian, medieval, egyptian, greek, pirate, they have them all! LOL And each one has different shows/attractions that you can do while in each one. The Forum shops at Caesar's Palace is really fun and cool to wander around in! I know what you mean about rather going to Disney. That would be my choice too!
