I got really good airfare today with Airtran (884.40 for 6 seats). Now we want to find a good rate for a rental car. I found a code on mousesavers.com for Dollar. If I use the code it gives me a good price. For a minivan 8/21-31 $471.79 with the code, without code $619.01. Pretty big difference. My question is will they ask for any kinda proof for this discount? Proof of somekind of discount program like AAA or something similar. Should I use the code?
