Id say so. This was my third trip to Vegas, but the first time I really rolled DEEP and actually did the damn thing proper. There was like 12-18 of us between Aria, MGM and Tropicana (flew in from NY, DC & Boston). Diff personalities, but all mature and were down to have a good time.
Met ladies from all over..Ottowa, Calgary, Idaho, Wyoming, a gang from Sea, these fine sistas from Cle...oh and there were these sistas from the Bay who were talking to a few dudes in our group, they said they knew we were from the East Coast cuz dudes out there dont just start conversing with them like that

. They were cool though, so Im not sure what that's about..
Anyway, back to your question: theres def some lowlifes in Vegas, but its not hard to avoid em, get into whatever you feel, and have your fun. Just go into it with some idea about how you want to spend your time, and execute.. Having said that, I know I wouldnt have gone as hard as I did had it not been for my boys having ideas/plans/party option lined up, so Im thankful for that, cuz this 3rd time really opened my eyes to how down these chicks are out there..
