I went once when I was first married. And I HATED it. I was taking a course and H was cruising the strip clubs (should have been a clue). And I thought the food was bad and people were phoney but I did manage to see a show with the Carpenters and David Brenner on the same bill. 2 years ago I saw David Brenner and we talked about that show. He ended up talking to me for twenty minutes about Karen and her anorexia. It was like we were old friends!
I went to Vegas with friends and my daughter (baton twirling event) from 2001 through 2007 every year (the event was in France this year). We've stayed at some nice hotel (and one I wouldn't recommend), have found some fab restaurants and seen many many of the shows. Be sure to book some shows - you should do this soon.
So, for sure ask me anything and I'll give you my advice for sure.
