For my San Diego Area families:
If you have a Birch Aquarium Membership you get free admission to The Wave Waterpark in Vista, CA from Mid June through Mid July. A Birch Aquarium Family Membership is about $80 reg. price. But they always have deals on www.livingsocial.com for like $50. Reg admission to The Wave is $17 per person. So for a family of 4, it's a really good deal! My kids and I will be hitting the waterpark next week...woohooo!
This information was sent to me via a members email from Birch Aquarium. You won't find this deal publicly listed on any of the websites.
