Here are my thoughts on the sets:
The Buggy: My least favorite, this set is boring.
The Subway Station: I wouldn't call it a station, its more like subway tunnels, but I like it.
The Portal: I like this set and hope it connects to the Subway set, I'm also glad it has regular ghosts.
El Fuego's plane: The planes a good build, but the sets a little boring.
Light House: I like the build and think it will go nicely with the Shrimp Shack and the Fishing boat.
Fair Grounds: This set reminds me of the UniKitty fair ground set. I feel like its not as good as the friends fair sets, the clowns are the best part of this set.
