eqwalker: You had asked about a theory on the numbering system. I had proposed that there may be a correlation between generalities in Zip Code area for the first 5 digits and priority of your order in the second 5 digits. I had assumed that the last 5 digits would have started with 00001. However, in knowing that yours was placed on the first day, perhaps the numbering sequence (in the very unlikely event that I am right) began with 10001. That would have made your reservation number 1173. More likely that is the case instead of 11,173. You are in Arkansas, right? The zip code location of 65737 (close?) is in West Branson, Missouri. Not a huge distance from Arkansas? Probably just coincidences...
