It’s the smallest land, but I wouldn’t say it’s too small. It feels Diagon-sized at the very least, but the other lands have massive footprints by comparison. Also, the small footprint makes the entertainment pop, it takes ten seconds to see Igor, then the violinist, then the Invisible Man, etc back to back to back and it makes the land feel incredibly alive.
Sightlines were my biggest problem with it, it’s very close to the hotel and you can see it from pretty much the whole coaster side of the area.
