You have two options, you could have one person make a few nights in the room, and then have the other person make the remaining nights. Just tell MS what you are doing and have the ressies "linked", or
you could transfer all the points into one person's account and have them make the entire ressie.
The only "combining" stipulation is that you cannot "share" points for a single night. If a gv takes 30 points for one night....all 30 points for that night must come from a single account....you cannot combine points for a single night.
