I am hemming and hawing about how much money to bring. Not counting the motel stay or the tickets I am prepaying for (with the Passport to Savings website) or gas, how much should I bring for 2 adults and a 10 year old for 4 nights, 5 days? We are eating breakfast and dinner (bringing snacks for in between). And will probably do a few things not on the Passport to Savings list (we chose 6 from there). We don't do much souvenir shopping. Probably spend under $100 on that kind of stuff.
