macraven, I called today and they allowed me to book 2 rooms with the APH discount. I let her know that 1 room was in my 14 year old daughter's name. She said she would put her in the room with the other adult (her nanny)so that both rooms could get the discount. I have a copy of the reservation, so we'll see.
Maybe they just meant that if you;re under 21 you can't book the room??
