Definitely ask for group rates. If you have 15 today i think you can get them. Otherwise, if you are a homeschool group you can get excellent rates for most off season Mondays and Thursdays. You just have to pre-register.
Online is $10 less. On some McDonald's with a purchase of a HAppy meal you will get a one child entrance with the purchase of a adult entrance
Call and ask for group rates
Adults are about $100 with tax...kids are about 90 with tax. There are coupons out there on select small lego packs (the ones in bags) that have free child admission with paid adult. Check online too.
