year before last i started my stay at rpr on january 2nd and it was tough hotel and park wise.
crowds didn't let up until about the 6th.
i would have to look at a calendar to see how the days of the week will be for this year and next before i give a statement on what it could be like.
are there 6 in your party?
or is it just you and the 4 kids?
express lines were beneficial during the period i was in the crowds but the park itself was at a high crowd level which effected walking and getting something to eat there.
it was doable but wasn't used to the longer waits at some places.
from christmas day to new year day, room prices are much higher for the onsite hotels and parks tend to stay full.
if you have been to any parks during the week after christmas, this might not be any issue for you.
