Every year right after the last night of Halloween, the Magic Kingdom goes from ‘Boo to You’ to ‘Once Upon a Christmastime’ almost over night. Thanks to nearly a year’s worth of preparation, the lion share of work is accomplished in one night. It’s all thanks to Disney’s hard working holiday services cast members and a lot of coffee.

Thanks to Disney, we get an up close look at the work that’s involved on the first night of transformation:

We had a great night at one of the year’s first Mickey’s Very Merry Christmas Party’s of the season. Disney’s operations team has the party down to a science and even though the park was crowded, it never felt overwhelming. The best advice is still to arrive early and stay late. Lines for cookies and drinks were pretty much gone by 10pm and even most of the character photo ops had shorter lines by then too.

I really liked some of the little touches that they added to “Mickey’s Most Merriest Celebration,” now in its second year. Holiday Wishes fireworks is as lovely as ever, but could use some upgrades in the projection department next year. The Parade remains the big attraction and street-side seats go quickly even though the parade schedule has been pushed back.
