It's Kind of wonderland. When I was in Lotte World, I thought I went to the future because all games and entertainments was by using VR devices. It was interesting to play with VR devices.
Lotte world is huge!! I went on a Friday and spent an entire day there! Despite it being a weekday, the place was super crowded. On average I think I spent about 1 and a half hour queuing for each ride. The queues can be quite painful, but the rides were well worth the queue. I would suggest reaching Lotte World the moment it opens and going straight for the few rides you really want to go for first. Because the waiting times for some of the more exciting rides become 2 and a half hours later in the afternoon. There are many restaurants in the theme park too and they are surprisingly not expensive. Also, weather is not really an issue since most of the rides are indoors! Overall, I had a great day there. But it was really tiring to queue though.
Unlike other theme park, this place is conveniently located in Seoul city center. So this place is great to visit because of easy access by public transportation. And its rides are very exciting too! Good place for both children and adults. And also, the aquarium is near so if you buy lotte world and aquarium combo ticket through baynaru, you can enjoy both place in reasonable price.
I really recommend to visit this place early in the morning, because you'll want to stay about the whole day in there. There's a lot to see and a great number of exciting attractions. Try the character waffles outside the main building, they are delicious!
Buying on Baynaru is cheaper than using coupon on the site.
My daughter loved a pair of Beluga, a white whale at the aquarium. Whales with friendly faces :)
