The good Legoland I thougt Legoland was a really fun experience. Going in the winter time despite the weather was probably the better choice as the park was fairly empty. Minimal to no waiting at all. I arrived at 10 am and with 3 kids was unable to attend every attraction. Most attractions everyone can ride. Although there are a few with height requirements. It's basically designed for a 3/4 year old to enjoy the whole park.

Legoland hotel The rooms are fairly small especially for the price. The themed rooms were a nice touch to include treasure boxes and a good supply of toiletries. The hotel has a restaurant and a buffet style restaurant. They have a workshop where the kids can learn to build something. There is a kiddie pool as well it's deepest point is .6m so safe for all. There is a small shopping district next door with all types of food.

The bad. The things I really didn't care for predominantly revolved around money and convenience. In which I really didn't have any gripes with Legoland per se.

I was surprised by the price gouge in everything to include Legos in the Lego store

The restaurant inside the hotel was 4000 yen fir adults and 2000 yen fir children for a very mundane menu. Also everything had specific hours. This included makers pier. So it's easy to miss a dining block and then resort to eating at the hotel. Also because Legoland is in an industrial area there aren't any stores around. My biggest gripe was parking. Legoland to include the hotel had no parking so you have to pay for it out of pocket.

My last issue was despite a fairly mixed customer base the staff's overall English comprehension was extremely minimal. I'm curious how someone who didn't speak Japanese would fair

I'd come back but would plan differently
