I think it's definitely worth the trip. Thirteen years ago, my company organized a group trip to Discovery Kingdom, but I was pregnant at the time and missed out, which was quite a shame. Finally, today, our family of four was able to make the trip. We even bought children's tickets for 39 yuan. I used my teaching certificate to get a ticket for 9.1 yuan. My husband and eldest daughter bought teacher and family tickets for 130 yuan each. For a full day of fun, our family spent a total of 308 yuan. It was a fantastic deal. Yesterday, it was cloudy, so the park was incredibly quiet. The lines for popular rides were only 20 minutes. For rides like the roller coaster, the pendulum, and the long, spinning ride, there were no lines at all.
My youngest daughter is 155cm tall, and she enjoyed all the rides. I've read reviews saying that many of the extra-cost rides were bad, but I didn't feel that way because we were overwhelmed by the free rides and didn't try any of the optional ones.
If such a good deal is available in the future, we'll definitely go again. At the end of this winter break, we went to Universal Studios Beijing, and our family of four spent over 1,400 yuan on tickets. Discovery Kingdom was a much better value for money.
