We were there this past Thanksgiving week, arriving on Sunday and leaving on Saturday and found the crowds to be moderate on Sunday, Monday and steadily building until we left. Wait times on the main attraction rides were anywhere from 30 to 90 minutes in the afternoons up until Wednesday when wait times increased substantially. I remember the wait time for Mission Space on Wednesday afternoon being posted as 120 minutes and I believe it was even longer for Test Track. We hit those rides first thing and in many cases walked right on in the mornings and then grabbed Fast Passes to come back later and ride again. We thought it was managable. The weather was beautiful, mid- 80's most days until a coldfront came thru Friday night. Almost all the Christmas decorations were up and they finished them up Thursday night so that was really nice to see. All in all we had a great trip and would go again at this time of year.
