Phuket I did 2 years ago. I stayed near the airport. It's ok. Before that I stayed in Patong. Lots of nice food in the back sois.
I have gone off beaches a bit. Prefer the cities now. My last trip was all Isaan plus Bangkok.
My next trip is Chiang Mai, Ayuthaya, Isaan a bit. Maybe a road trip up north.
The mrs loves Chiang Mai and so do I. So a fair bit of time there. We also like Udon.
