I have had my GP number added to my PL reservations using 800-checkin, general reservations, and at check-in on several occassions. I never had a problem using any of these channels. </font>
I'm not even so concerned about my GP number per se, just being able to use 1-800-CHECK-IN to secure the right kind of room for the stay (King vs. 2 Doubles), but it doesn't sound like that's a problem.
