If you have kids they will love the Aquarium.  Although it doesn't come close to compare in size to the Boston aquarium, the quality is there!  Kids love the touch tank, where else can you touch a shark!  The "mystery" discovery boxes have the kids sticking their hands in and guessing what they are touching, again and again!  And don't forget coloring from the raised sea creatures outside on the deck.  You can't beat the location.  Be sure to pack a picnic or snack to enjoy on the outdoor tables overlooking the entire harbor.
