I need to book a premier in to break up a long trip. I am a single parent to 2 disabled/Sen young adults. We need to share a room but when I go to book it won’t allow 3 adults in a room, only 2 adults and a child (under 15). Will I get away with saying one of the DC’s are 15? Surely a family room that sleeps 2 adults and 2 children is fine for 3 of us?
