Made a 4ft square table out of wood and put it in my basement. Finished the Astronomy Tower and added it to the Great Hall, Whomping Willow and Clock Tower Sets. Ive set up a small track for the Hogwarts Express that loops around the 4 larger sets that have been recently released for the line. My 5 and 3 year old girls love it even if they haven't seen any of the movies and we have yet to read them the books.
I figure it will be a seasonal table we can swap out a display. After Halloween, i'll be turning it into my Winter Village setup. Later today Ill try and get a picture of what we have so far, but its very "played with" and not as pretty, but it makes me glad they they're happy.
