sorry,i'm a bit confused.
so it may be cheaper to book a room with park tickets than room only with ( up to ) 25% off using the AP ?
i know from reading other posts, that some people have booked a room for one adult ( with 1 park ticket ) then added other family members to the booking once it's booked. I've tried pricing like this also, but the prices seem to be by the room rather than no. of people actually staying in the rooms.
if you all have APs, it might be cheaper booking the DCR for one adult on a package (and any free children ie kids under 7) and then you can add the other members of your party to the cabin when you arrive. You only pay at the most 2 euros per adult per night booked if you do this.
The room only AP price you get over the phone with Disney may be more expensive than a one adult package, so get the price for the one-adult package online before you phone .
