Just as a point of information to anyone who may be interested.  I entered Thailand at Phuket with no problems.  I was not asked for any proof or documentation of finances or flight out.  I believe this was due to 1.  my having pre-booked a hotel which I put on the immigration form as my address  2.  also, I put their phone number on the form.  I suspect that people who are asked to document finances, and or transportation out, either do not completely fill out the form, or, sorry, don't look or act the way immigrations profile says they should, right or wrong as this may be. My passport was stamped departed when I left, at Phuket.  Since I entered visa exempt there was no need for a reentry permit, I believe these are for people who are on a visa. Upon my return, at Bangkok, from Cambodia, I was again issued a 30-day visa exemption, I am currently in Chiang Mai.  In case anybody thinks I am, or dress as, or even look like an extraordinary, rich or famous person, they would be hugely mistaken.  By the by, I did list my occupation as a firefighter, which is true, and wore a fire dept. T-shirt while flying, which may or may not have helped.

Thank you, I have never been to Thailand, I am entering by air, leaving by air and returning the same way,  and I am an American.  

The question is not about the original entry, its about THE RE-ENTRY! 

I will be traveling to Southeast Asia soon, visiting Thailand, Cambodia, and Vietnam.  I am going there from a country whose citizens are allowed entry into Thailand "Visa exempt".  What I want to do is enter Thailand first, stay a week, exit to Cambodia for a week, and return to Thailand for another week.  What do I need to do to accomplish this?
