This is a great place but it's small. You will go through it very quickly. For the price they charge and how quickly you move through it I think its a bit expensive. Once you've done it once, there really is no need for a return visit.
That being said, if you are there on vacation it is a great way to beat the heat for an hour. They have a touch tank and at scheduled times throughout the day you can witness animal feedings. If you check out their website you can find activities like back-stage tours and toddler activites.
I live in the area and go about 2 times a year. I started taking my daughter at about 2 she is now 5 and still likes to go. I would think that at about age 7 interest may start waring off. It is very small in comparison to other's, however I always felt safe letting her walk around on her own exploring. It is clean, the staff is knowlegeable and there are plenty of coupons out there if you look usually with an adult you can obtain a freebie for your child. The have touch tanks and feedings scheduled daily. One downside to this being on the boardwalk during the summer season, parking is expensive. The few free spots that are in town are typically taken after 9am. The upside if you are going to the boardwalk anyway it's a nice side trip that can be done in a short amount of time.
I honestly wasn't very impressed with the Jenkinson's Aquarium and neither were my children as a matter of fact. Let me just warn everyone that for the prices they charge for admission, it is not worth it. The staff is not very friendly either and the schedules for the day are very misleading. My kids were beyond ecstatic when they saw the advertising for seal feedings and pettings. They wouldn't let it go, so I decided that it would be a nice diversion from the blistering sun. And let me say, the air conditioning is this place is the best part of the experience, and that's not a good sign. It turned out that there was no seal feedings, or pettings. The signs were false and they couldn't explain themselves. My kids were let down the entire day, but one thing I have to give them besides the heavenly air conditioning, is that they have nice looking exotic fish.
My kids love aquariums and when we were at the shore last time we decided to go in to break up the day. it was cute, but I didn't think it was as exciting as we had been told. I think it would have been better for younger children. We didn't get to see any of the animals getting fed, so maybe that would have added to the experience. I think the $10 admission was a little steep for what it was.
With so much to do on the boardwalk, this is a nice way to relax, instead of going from game to shop. They have a decent collection of fish in a well laid out aquarium. The little ones really think it is a treat to be able to actually see the fish while they are at the shore.
This aquarium is pretty nice. They have a lot of different animals. There is two levels, and upstairs they have a touch tank! It's not that big so when you go you will get to see everything. It's good if you only have a little bit of time but still want to do something. It's right on the boardwalk, so you can also have fun there, or go on the beach. They also have programs like junior keepers, and penguin feedings.
