Dear Karn,
I wish I could go with you guys, but bad timing for me!
You see, my Thai friend from California will come and stay at my cottage with me on the nights of 18th and 19th and will fly back to BKK on Sat. 20th morning. So his schedule is not going well with your plan especially on Sat.
So I have to skip this Pai trip with you guys to take care of my friend. But on Sat. night you guys can come to rest/stay overnight at my cottage if you want to. there are 3 single-beds and 1 sofa for you guys to sleep on and have a full rest before drive back to BKK. My wife and our 2 ladies friends from California will arrive at our cottage in the morning of Monday 22nd. so I'm sure I'll have plenty of time for cleaning up.
Please let me know ASAP OK?
