LegoLand California was PERFECT for my kids. It wasn't too big for them like I thought Disneyland would be, there were rides, shows, and things for the kids to do. There was a water park, water rides, and a SEA aquarium. It was GREAT FUN! The only downfall I saw was we spent too many days there, (I was done after day 2 but the kids weren't) and Rysa was too small for some rides. A lot of the rides kids had to be at least 34 inches but some rides, like the roller coaster ones, the kids had to be at least 42 inches and some even had an age limit of 4. With those with the age limit, we just told them Rysa was 4 if she met the height requirement.
There was an area where you could take Lego's and build a car and then race it to see how fast it was. I enjoyed just resting in there while Cris showed Cayten what to do. Cayten loved building new things in all the areas they had legos. (Another nice thing (sorry posting as I remember) was with the rides that had REALLY long lines, they had lego areas where a parent and the kids could play while the other parent stood in line.)
