Visit Thailand, Vietnam and Taiwan

Any Shenzhen expat planning on visiting Thailand, Vietnam, and/or Taiwan this July? I'm looking for travel partners or a tour guide group. Any advice or suggestion is appreciated.

I have some advice - Don't form a group.
Been there, done that, never do it again.

The problem is everyone has to bend their plans so nobody gets what  they want.

I also want to travel to Thailand, want to eat mango and durian, there are a lot of delicious food, but also I like shopping.
