I've never been during the Christmas season. Is it better to make reservations for meals ahead of time for a party of six? We are used to going to UO during the summer months and don't usually have to plan ahead.
That's a weekend, I would make some reservations. We were there over a weekend in Sept and there was a half hour wait at Mythos for walkups. Though with an onsite stay, you are supposed to get priority seating I think?
The week between Christmas and New Year's is crazy but before Dec. 20 or so, it is very quiet. Express passes are at their lowest price until the 20th.
