We went this year for Thanksgiving. It was our first time at Disney during a holiday week. We had decided last year as a family to go to Disney specifically for the Thanksgiving holiday.
Yes, it was more crowded than we have seen at other times of the year we have visited. What we noticed was that it got busier the closer we got to Thanksgiving Day.
We took advantage of EMH in most of the parks and got to do all of the major attractions. Some of the family went golfing, some of the family went to the water parks, some stayed by the pool.
We had a pretty aggressive touring plan so that we could get all of the major attractions in, but we built in free time and down time. too.
We had a wonderful time together eating dinner at the different resorts and also checking out the beautiful decorations.
We would go back again for Thanksgiving week. It was great!
