Tentacles - How many Aquariums do you have?

I checked London and New York and afaict both have like 1 aquarium (if you search on maps you get several, but everything else is a shop or a repair company).

There's about 3 (new york) or 4 (london) amusement parks, but only just in the 15m radius. Presumably on the medium/short games the radius is a lot smaller.

Museums and Hospitals _maybe_ OK, but depending on the short-game radius might not be.

I was surprised at the categories, they don't seem very frequent, or maybe it's a non-UK thing?
