This was great - I'm a new DM running what was more or less my first adventure. This provided a lot of recognizable content and thematic elements that were easy to riff with. Overall we played for about 4 hours and the players were giggling throughout.
I had to encourage my characters to make some extra rolls, just to expose them to some of the underlying fluff. In addition, I had to make the christmas tree map substantially bigger to account for the size of the awakened tree - which was pretty tough for lvl 2 characters, but there were enough of them to take it down.
