Went to the Aquarium recently with my wife on a trip to Boston. We enjoyed the experience, despite the fact that the place was immensely crowded. There's much to see, so I would recommend that you go a bit on the ""off-hours"". Otherwise, you're pretty much breathing everyone else's exhaled breath for the duration. I'd still return! You should check around for deals, i.e. combo-packs for the harbour cruise, aquarium and trolley, as it ends up being a bit cheaper.
Pros: Exhibits
Cons: Crowded
