Ah, yes, I have read the entire thread. Vroom is an agency that searches for good rental prices. Their code is no different, in reality, than using a Costco code or any other code.
If you have questions or are unsure about any code, my advice as a "Disney veteran" is don't use it. If you make a mock reservation using the code given here, it comes up as Vroom, Vroom, Vroom. I went to the Vroom, Vroom, Vroom site and that is the information I found for that code with Alamo. I am sorry if my trying to help has twisted your knickers. In the future, any questions you may have about Alamo, National or Enterprise will be ignored by me. Have a nice day.
sounds good thank you
