What should I know about cancelling my multiple entry permit and obtaining a tourist visa upon returning to Thailand?

The user's retirement visa expires on December 28, and they plan to depart Thailand for Malaysia on December 26, hoping to obtain a 60-day tourist visa upon returning. However, comments suggest that the user needs to cancel their multiple entry permit upon departure, and there may be complications in re-entering Thailand due to the expiration of their retirement visa. It is advised to wait until after December 28 to re-enter, or to seek a Visa Exempt stamp instead of a tourist visa.
