Is there a way to get discounted tickets to the New England Aquarium in Boston

We are going next week for my daughter's birthday but ti's so expensive.

You may want to put the trip off until September. Many people don't realize that their local public library has passes to many museums and attractions, including the Aquarium. Unfortunately NE Aquarium doesn't accept passes in July and August. The link shows a number of libraries and the passes they offer. http://search.yahoo.com/search?p=library%20passes,%20n%20e%20aquarium

New England Aquarium doesn't accept those free passes in the summer time. That is their peak time so they don't accept them then.

They only accept them in the fall, winter, and spring.

I have gotten passes for it before and it says right on them that they are valid anytime except summer time.

If you still want them for the fall spring or winter you can get the from your local library.
