I made a reservation with National about a month ago. Got a good rate with both disney card discounts. I went in to just check it today and the confirmation page came up with a different (higher) amt. The base rate was the same but the DC card discount was gone and the DC coupon discount was slightly higher leaving me with a reservation that was almost $30 more. I called National and the guy said what he was looking at was the same rate as my original rate and that what showed up on my confirmation today must be the rate charged today. He said I would get charged the original rate. I will bring my original confirmation sheet with me obviously but I am a little worried about why this other amount would even show up. Has this happened to any one else and was there a problem when you got your car? We don't go til Aug. so I won't know for a while how this will work out.
