I really like your family experience with the kids at the zoo, it is impressive that you managed to get the 14 year old to go with them, usually at that age they don't like to go with us on outings because they stay with their friends ha ha ha. I don't like zoos very much because I am a defender of nature and the free life of animals but that zoo is beautiful and well cared for. Excellent choice plus a lot to learn I could love the galapagos and the meerkats my favorites very cute little animals.
Bring their friends ;D
The 14yo was the one that wanted to go to the zoo. If they have any particular interests or excursion preferences that's what we do if I can afford it.
I think any zoo or aquarium worth their salt has to be a centre for education and conservation these days. Having a horrible past doesn't mean they can't have a useful present and future, and I think anything that helps improve understanding and education for future generations of everything is good :)
Who doesn't love meerkats ;D
I'm sure there are some people that don't love meerkats but so far everyone seems to think they're cute XD
