Another nuance is that reservations use codes gp1000, gp2000, etc., but the hotels use two character codes. The hotel uses g1 and g2 respectively. I have tried to add GP1000 at a hotel and they didn't know how to add it but I later found out that GP1000 maps out to g1 on the hotels software. When you book on the web site, is there a field for the GP bonus codes or do you have to have it manually added? Also has anyone gotten gp1000/gp2000 and the 1000 online booking bonus for the same stay?
