Very worth it! We opted for this activity instead of Universal Studios Singapore since we've already tried it in the past. All participants receive a wand. As a Harry Potter Fan, it was amazing to be able to act like a wizard, do spells, find hidden effects, and experience the different locations in the movie. I also really loved the details that they did in each location. You could definitely take your time going around the different sets and enjoy each location. It took us walking around for 2hrs and 30 mins to fully enjoy the place. It is good for all ages, but do note that you will be walking around most of the time since it is a walk-through activity. My family members who weren't harry potter fans also said that they very much enjoyed the experience and stated it was the best thing we did during the trip apart from the meals we had! Very worth it!
