Pai is a funny place :')
I went there 2 times when I was living in Thailand. It's not the best place to visit but it's definitely a lot of fun! I stayed at Spicy Tao, got eaten alive by mozzies and spent the days driving around waterfalls and the canyon!
It definitely is! Luckily my hostel had nets with no holes at all so mosquitoes weren't an issue for me.
