I've got some reward certificates I'm trying to decide where to use - I can get $400 at Avis or $400 in airfare coupons. The airfare coupons are going to be a hassle 'cause I have to buy them through my credit card company, which means I wouldn't be able to get back credit for cheaper SW Dings. So I think I'm gonna do Avis... I'd still like to stretch the $400 as far as it'll go - any idea what a good price for 10 days worth of a full size auto would be? We're just going from MCO to Nick Hotel, then back and forth to the parks. No frills needed. Could I fit two car seats in the back of a compact?

Any advice would be greatly appreciated!
