I read a post and the comments in the Thai Visa Advice - Q&A last night. A Moderator posted this comment that I copied & posted below:
"Thai Immigration Officers are becoming more strict on questioning those who have been in Thailand using back to back visa exempt entry plus extensions.
Over 1,000 people at BKK Suvarnabhumi Airport Bangkok and DMG Don Mueang airport Bangkok were denied entry in the recent week. And returned to their initial flight departure city at travelers expense.
Mostly for multiple uses of the visa exempt entry with extensions.
Suggest you use a land border crossing if you try to get a second visa exempt entry. And use an experienced border run service company to take you with same day return.
They PRE-ARRANGE your exit and reentry to get the New 60 day STAMP as Visa Exempt Entry."
