Hi,
We are just back from our WDW trip. Our group rented a total of 3 cars, all using the code. There was no problem at all with the code. The only problems we had were related to the fact that there were no cars. When my parents arrived, there were no cars so they were told to take an SUV. They took a CHevy Suburban and the final charge was more than the quoted price. They are going to dispute that with National. This happened to me before and the quoted price was honored by National.
Also, when my family arrived at 10:30 pm at night (mucl later than my parents), there were NO CARS. I mean NO CARS. The only thing in site in the whole garage were a couple of 15 Pax vans, which we did not want. Someone finally drove up with an Olds Alero which we took. They then drove up a mitsubishi galant, and another car similar to an Alero. The cars were getting snatched up as soon as they brought them, because there was nothing in site.
Before everyone panics, we arrived on 11/6, the most heavily travelled day of what has become known as "Jersey Week".
