People go to Vegas to spend money. {Currently fiat} not to buy Bitcoins.
If you find a bitcoin user there on holiday, and he/she wins some money, they might invest some in Bitcoin, but the chance of that is low. The whole Vegas scene is setup for people to spend money, not to buy investments in crypto currency.
On the other hand, if merchants there start to accept
BTC and ATM's are regularly availlable, it might stimulate a need for the currency, and people might convert their fiat to
BTC for that purpose. {The only question would be, why would they want to do it, if fiat and other payment methods are availlable?} Only reason I can think of, is ease of use and it will be cheaper, due to low transaction fee's.
When people are in an environment like that, they tend to not think about cheaper alternatives, and the "holiday" feeling cloud there judgement. {They normally spend more than what they would have spend, when they were home.}
