The underground river tour was amazing. Did not encounter any problem at all. However, the firefly watching tour is the exact opposite. Didn’t get to experience it with my mom because the van driver proceeded to the venue without us. According to him, he couldn’t contact us which is unacceptable. The whole time I had my phone with me so I could easily pick up the phone once he arrives and I can receive texts or calls from other people at that time. Well, good thing is they refunded my payment.
