I rented a minivan from National for 9/18 - 9/23 a few weeks ago. The final total for the reservation came to 210.96 (using Disney Club discounts/coupons). I do have the reservation e-mail printed out to take with me. When I checked the reservation today the total was changed to 248.06! How much of a hassle is this going to be to get the first quoted price? I was hoping to bypass the counter as the reservation is with Emerald Choice. Any suggestions/words of wisdom from those experienced with National would be greatly appreciated.
