You have to call Chase's Cruise & Tour Dept and make sure when you purchase them you tell them you want tickets direct from Disney (they will sometimes try and get from Funjet vacations I think and then you don't get the #'s to link them right away).
If you have the CSP the UR's are worth more at 1.25 value and if you have the CSR it is 1.5 value. Great deal if you have the CSR.
I just transferred a Carnival Cruise to Chase using my UR's. I have the CSR so value was at 1.5. So, got $3000 of the cruise paid for with 200,000 UR's. So a savings of $1,000. I plan on doing this in the future for Disney Tickets. No where else can you get this savings. (now I just need to build up my UR's again...)
