Update:
Legoland was a blast...for my 5 year old.
It was pretty dead the day we went (Though sunny and warm). Zero Lineups, Zero Waits. We even went on rides over and over again because my 5 year old couldn't get enough.
It was almost creepy and sad just how vacant the park was. Im sure on a weekend or summer it;s jammed packed.
All in all, if you have kids 4-7 or 8, they'll love it. Adults-Meh, but when you see the joy in your kids face it doesn't matter.
All in all, we got their by 9:30, and by 2:00 we had hit every ride (sometimes 2-3 times) and it was a pretty relaxing day.
