just yesterday i "modified" our BRP poly ressie (originally nov. 3rd-nov. 13th)! i added 6 nights to the beginning of the ressie, and canceled the last 6 nights (so we're now oct 28th-nov7)! it was so easy, i got the same BRP rate, and because i was keeping the same number of nights, there was no change fee.
i initially asked about adding those first 6 days at coronado springs (imagining we'd have to do 2 ressies), thinking there was NO way they'd let me add days (as i am SO FAR from 60 days out), and that there was NO WAY there'd be availability for rooms at the poly with best rate...well, not only was there no problem with booking the rooms at the poly with brp, but the computer system was going to let me book a room at the coronado springs with the BRP, adding it on to my existing ressie!! the CM told me this was some sort of glitch, but she said she'd do it if i wanted (which i didn't! i 'll take the poly!)
fyi,
she did say that there was a $60 change fee ($50 fee plus $10 processing fee) if i modified my ressie and it was less expensive...
not sure if others have/will have the same good luck, but that was my experience....
(EDITED TO ADD: I USED THIS #:407-939-7675...i got this # from someone else here. both times i called this #, the CMs were quite knowledgeable about the BRP, which i think is not always the case when you call CRO)
pixie dust for you,
