I've done the Holiday Tour a couple of times and it was really fun. I remember we got to go on Haunted Mansion Holiday, It's a Small World Holiday, and have priority seating for the Christmas Fantasy Parade. We also got hot chocolate and a gingerbread man cookie. Another time I got a snowflake rice crispy.
On the tour, the guide told us about the decorations that they put up around the park and how different ppl celebrate the holidays and stuff like that. I really liked going on tour and hopefully I'll go again this year!
