We were having trouble with the minimum spending for going on a long-time trip, and so our friend that is traveling with us kindly decided to help us out by opening this card with the $75k bonus. He also plans on getting the Reserve card and giving us the 2 free weekend night certificates.
I know its possible for him to book us a room by putting us in the Guest 2 (and we're traveling together anyway), but could we somehow book the first 3 nights of our room with his points/free nights, and then book with our HHonor points for the remaining 3 nights for our stay? Will we be forced to move rooms (since we'll show up as separate reservations)?
