We were there last Monday, opening day.
We waited just over an hour for the opening cerimonies (I know it's spelled differently) then all the vip's had to go first. All together it was almost 2 hours before we got in.
My son 11, loved it. It's very well done, laid out, kid friendly.
While nice to see I don't know if it's worth the $18.95/adult, $11.95/kid to get in. Unless you have a hopper it's only one time thru, once you're out that's it. And I forgot to use my $3 off coupons.
Legoland was very busy that day as well.
