The coolest part of this program is "Eagle Feeding"! There are truly a lot of birds, dozens in one place (and in their "normal" lives, they are solitary; I'd never seen more than two at once before!). There's plenty of time to observe and photograph them, especially if you have good optics.
The next item, "Fireflies," was a disappointment. There were very few fireflies, at most a dozen visible at any given time. For fireflies, I highly recommend going to special, separate locations in Selangor, where you'll see hundreds, and you'll be taken by a paddle boat, not a motorboat. Kampung Kuantan Fireflies Park is one such place.
The last part, "Blue Tears," is truly magic in real life, especially if you're lucky enough to visit during peak season, with a high tide, and a lot of luck. I wasn't so lucky; it was what you'd call "minimal," but even then, everything looked very cool and unusual. It's something every nature lover should see at least once in their life.
Considering the cost, this is overall an excellent excursion.
