Me and my wife bought these combo tickets a week and a half before we visited Lotte World. The tickets were about $52 USD per person. With these combo tickets we were able to visit Lotte World Adventure amusement park, the aquarium which is located in Lotte Mall on the first floor, and go all the way to the top of Lotte Tower to the 121st floor. We did all of this on New Year's Eve and we had a lot of fun. I highly recommend these tickets if you are going to visit.
