Really disappointed in the holiday festival.. we came two nights once on Saturday and then on Thursday and the lines are horrible. Two Hour to three hour wait for each line (getting tickets, Santa, and then the train)-even on a weeknight. The only line that wasn't bad was for the carousel, but you need tickets to ride the carousel -which you must wait in an hour long line to get tickets- which wasn't going to happen. We skipped the train, because while the train probably is fun.. my three year old will not wait in a line that takes three hours, no matter how exciting the train is(which it's only maybe 5 minutes-so not worth it). We did wait an hour for Santa, but not sure it was worth the wait.
I would skip the park during the holiday lights.. and come when it's over, because then it's not too bad.
