I'm actually heading up there next week with my 2 yo son (not the best companion for a full day's activities!)
I was looking at buying a Season Pass for me (They're $108.00 for adults) as a one-time entry is $48.00 anyways.
That way, I can go up whenever I like to spend the day looking at Herps, and we can go up together whenever he likes as it's still free admission for him!
So, providing you're not thinking next week, count me in.
Were you thinking of a get together afterwards, or just play it by ear?
