I'm a partially disabled retired Vet over 65, how much is entrance fee to the acuarium and Butterfly house and are they both in the same building?

Over 65s get a $2 discount, so $27.95.

I was just at the aquarium less than 2 weeks ago. My girlfriend and I were quite thorough, I do not recall there being a Butterfly Room. I'm sorry if I am wrong but this was my experience.

For adults it's 29.95/person and that's for the entire exhibit
