YES, I went to Hatyai recently on 11-13 Mar (huh.. 2 months ago). We joined the tour with only RM170 per pax for 3 days 1 night journey. The whole journey takes about 7 hours from KL and I didn't slept the whole night (just can't sleep!!).

First stop: Wat Tham Rou Chang
This temple is located nearby the Padang Besar immigration checkpoint and takes about 20 minutes

It is believed that one traveler discovers this temple that is inside a 'cave'.

The 7 'head' dragon.

Kuan Yin statue and drawings inside the cave.

We then proceeded for lunch at nearby shop at roadside. My fellow blogger, Kelly was furious when we are going for 'chicken rice' and noodles. Maybe it is just too simple and what is difference with our country's version?

I can say it is average and costs us 40 Baht.

Second stop: 

Next stop: Wat Pah Koh Suwanaram temple

Luang Phor Thong (Archan Thong). A holy monk that can foresee people's future, cure black magic, business prediction and many unforeseen power. Even though he's passed away but they said his hair is still growing. His body was over there since 2000 and until now it is still in good condition with no foul smell. Amazing!!

This video show casts the holy monk.
