We are considering getting an annual pass for the family either for the Zoo or the Gardens by the Bay or the SEA Aquarium - we have a six year old daughter who loves animals and plants. Which one would you recommend?

I also recommend getting an annual pass for Friends of the Zoo! There are a lot of things you and your family can do. There are various animal shows as well as special interactive activities that they offer. And since your child loves animals, she'll surely enjoy the Kidzranger Tour wherein she can experience being a zookeeper and groom those cute bunnies and feed the hungry goats! Here's one of the links of what your daughter can experience and learn: http://www.zoo.com.sg/special-experiences/kidzranger-tour.html#ad-image-0
