I do the same each year via a non imm o-a multi entry visa. No border hops and no dealing with immigration except for the 24 hour and 90 day reporting requirements. It keeps things simple for me while in Thailand. I get a new one each year because I do not want to be beholden to enter by dates when making our travel arrangements.
Tony Rimmer after getting hassled during my 90 day reporting for not filing the 24 hour report a few years back, Korat immigration is my first stop within 24 hours of returning to the country.
Perhaps you may want to take a look at your passport and let us know exactly what type of visa/extension of stay you have so precise recommendations can be provided.
Mary Hanson She is applying for a non imm o-a multi entry visa. There is no requirement for funds in a Thai bank with this visa. That is one of the benefits of using this visa.
Actually the unlimited entries are available up until the enter before date stamped on the visa which is one year from the date the visa was initially issued. After that date you must purchase a reentry permit.
