We arrived today in Woodbridge around 11:40 AM & were let in around 12:15 PM.
It was nice but crowded.
For anything interactive like feeding, holding animals, etc. you need to buy tokens which are $2 each but get cheaper if you buy packages.
I can post exact pricing, if there's an interest.
If you can say no to your kids, or at least limit the tokens, it's really not bad.
