I'm going to travel to Chiang Mai from Jul 11 - Jul 15. I'd like to book your Skyline Adventure package for 1 - 3 person on Jul 14. However, when I looked up at the website, the booking system was under construction so I'd like to ask
How can I make a reservation?
How many days before the trip I should make the booking?
Is it pre-paid or post-paid?
