I purchased an annual family pass, and happy that we did. We've only visited the Springs once so far, but I was happy with our first trip there. We spent about 2 hours and only scratched the surface at what is offered there. My kids liked cracking their own geode ($2/each for members), and lots of trails to wonder through. They were kind enough to let me purchase a separate ticket for my sister who was visiting from out of town at the local rate, and that saved about $10. We can't wait to go back, and also visit during one of their special events as well.
