Hello, We have been to DL twice, both times at Christmas, our first day being Christmas DAY. This year we are going again, over christmas, except it will be 21 on. I can't say what it's like compared to a regular time of year but we LOVE it christmas. It works for us for a few reasons, husband is a school principal so he has it off, we make sure we are there over christmas day, therefore we buy NO presents for our 4 kids or ourselves. I tend to spend alot on presents so that money goes towards DL. It is SUPER busy, super busy. Our last 5 days the park closed 3 of those days due to capacity. However, if you know it's busy, your ready for it, and it's DISNEYLAND... how can you be crabby It really IS the happiest place on earth!
