i am booked in for oct for just me and ash but my sister was thinking of coming along if she could save up some money. she is only leaving school this year so will be trying to get a job after her exams. just looking at the disney site the price for my trip has gone up. would disney just add her onto the booking or would they treat it as a new booking and therefore i would lose the 40 percent discount i booked under kwim. what are my options here? could she get an ap and stay in the room or would she have to already have one to do that?
