I've spent $500 dollars total on my trip to San Antonio in February, but I budgeted for that. I have to agree with Raven that if it's money that's needed for other things (like bills, rent, etc), then you might want to think about it first. If it's a budgeted item and you have the funds to cover it, then go for it.
Mayhem is in my town this time, so I won't be spending as much, but it's still in the budget. And I fully intend to have a good time!
