OP will have no problem, but for safety have cash ready to show (THB20k), and onward travel ticket (this also required when you check in and enjoy. On a positive note we had a customer that did a OUT/IN straight after a Non B with WP and he had no problem at DMK.
OK, before that topic spreads out of control I close comments. This is thai visa advise and the only advise I can have have your three things in order or teh right visa. A guy in a wheelchair on tourist visa, but has family in Thailand. .
no, they not issue. Last week we had one Customer 54 years of age, they said you strong, can work, needless to say they guy was pissed, he even refused to take the tourist visa he was offered. For Tourist they enforce strictly the PROOF OF FUNDS and onward ticket occacionally. On a side note they also start to give "Reminder stamps" out that Tourist visa are for tourist.
