Coolidge Park has splash fountains for even the youngest of walkers and right next door is an amazing wooden carousel.
So don't just go to the aquarium - hop across the river to Coolidge park.
There is a free trolly bus but bring a towel and maybe change of clothes, they don't like dripping wet kids.
