Room is paid for and tickets are in hand so how much actual cash should I take with us? I figure just about everything we need from food to gas can be purchased with our debit and or credit cards so why risk taking much cash? How do you guys do it. I was thinking that I might just cash in the change jar which has about $150 in it and just use the old debit card for everything else. Is this a bad plan or not? BTW, I can't believe how soon it is until we are THERE!!!!!
