I don't think so, if they set up the system the way as a Data Modeler (yes my day job) I think they should have to. The user generates reservations and each reservations will have certain types of properties (ARP, Discounts, Upgrades) that can be flagged, and then they can check the totals points of those reservations during the booking process to check that you do not exceed the total of points that apply to VIP. It has some backend calculations to do, but only a bit more buckets than they had before. They already know which buck if the current year and which ones are saves points from previous years. So it they built the data base right, it would not be difficult. Now of course this is Wyndham's IT department, but they have the bucket of points system working fine, as far as I can tell.
Funny thing however, I have yet to get the email.
