Legoland is ne of the VERY best place to take kids under 12. We went there 3 years ago when our kids were 2 and 4 and had a GREAT time. We've been dying to go back ever since and finally are going over this spring break. This time we plan to spend 2 days...1 was not enough last time. We spent time in San Diego, Carlsbad and Newport Beach. For beach fun, Newport was the best!
