The entrance fee is 350 baht for adults and 150 baht for children under 13.
Advance reservations are required, often a day in advance.
There is a minimum spend requirement in addition to the entry fee.
I have been using it now for 3 months and it saves me so much research. Reduces the need to call and double check every time.
How did I not know these places existed?! Atly's scoring is a lifesaver, now I can finally find THE spot without wasting time Googling my life away.
