Doing 3-day 1 park per day this time and will spend 2 full days in Disney and 1 in DCA. Hoping to be able to ride ROTR both days we are in Disney, but we'll see what happens. We have a group of 21 people going and are trying to determine if our odds are better linking all 21 together or just splitting up in smaller family groups. We understand w/ the smaller family groups we likely wouldn't be riding together, but concern is that w/ a party of 21 it would increase likelihood of there not being enough space for a larger party until later in the day and end up w/ too high of a boarding pass number as a result. We'll be there during the week so hopefully the crowds for it won't be quite as bad as what I've seen from Saturdays/Sundays.
