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 strongly recommend the multi Parks one for Zoo. I have Zoo and Gardens memberships for both my Wife and myself. Little girl still can go in free. But every time we go zoo or river safari, can go to a few places and then go back earlier. No so tiring and can keep going back. U will get sick of gardens if u go too many times though very cooling place to spend hot days in.
