The best time to get it? After Halloween. Not specifically November 1st, but sometime in November and December. I just purchased mine today and it is valid through March of 2018, and only paid $109 for the whole family (rides included). When we were there saturday, it was $125 and only valid up to next march (that’s five months, and all of them during the cold months)!!
Our first membership was purchased during Boo at the Zoo four years ago, and only cost us $69 for two adults (children under 3 are free), including free rides. Since a renewal is typically more costly, we like the idea of letting the membership lapse for a year and then renewing it the next year . . .
What can I say, I’m cheap!
