This tour is a great option for a night.
Sri Shakti temple was a cool temple to visit, different from Sri Mariamman and Batu Caves that you'll see in other tours. Uniquely, it is not brightly painted like other Hindu temples. Very interesting to see.
Feeding/petting monkeys was a lot of fun; they are adorable and friendly. Costs maybe 1 or 2$ to buy food for them.
The restaurant was a Thai restaurant on the waterfront. We had sweet and sour fish, some kind of pork and vegetables, and fried rice (I'm guessing with Jasmine). Very, very good. It also allowed a fantastic view of the sunset.
We did not visit the lighthouse on Bukit Melawati. I'm not sure if it was from time constraints or some other factor. However, it hardly mattered as from the description of the tour, you can't go inside anyway.
The highlight of the tour was (of course) seeing the fireflies and the glowing water at night. I've never seen so many fireflies, nor have I seen water that glows as it goes into motion. I still don't know (and havene't researched) why it glows like that, but it's sure cool to see.
Finally, our tour guide Hery/Harry (not sure how to spell it, since we received emails from someone spelling it Hery) was a fantastic tour guide. Very funny and always joking. Excellent guide.
