Question: how much money do you need to go to vegas?
Answer: Re: How much spending money need for 3 nights? You can get by on a $1,000 for three days if you aren't a big gambler and eat at the less expensive restaurants. Everyone in Vegas gets a tip, so keep that in mind too. I budget $500/ day which is by no means on the high end of spending, but typically get by on far less.
