the guy with the gun, probably, rather than the guy dressed in pajamas.
the con is $180, hotel split 4 ways will probably come to $20-30 a night (if we find a cheap place, not one of those places conected to it, we should probably start that research now, just to be sure), which means ~$100-150. Plus meals (eating cheaply means ~$6 a meal, with 3 meals/day for 5 days, that's almost $100 for food, and I know at least one meal I'm gonna want to eat nice. Plus shopping. The minimum you'll get by with is $500, unless you stay at a friend of Stacers', in which case you might do on $350.
However, when travelling, you should Bring more money and less clothes." You can get by on 1 suitcase, but you'll want a way to spend more than $500. I'd plan $650 at least, and bring a CC in case you need more for an emergency.
That DOESN'T include travel. ANd yes, if I'm driving, we will take turns paying for gas. We're talking 4 tanks of gas, I think, which in the Mazda is probably about $80. We'd let Gemm of light, being in NY and therefore much closer, would only have one of those.
We're not talking about something cheap, but we are talking worth it.
On the other hand, if you're very frugal, you can probably trim a lot of that off. You don't have to shop, you can live on crackers and water from a grocery, and save a lot of money.
