a) Massage class DTV?

b) if DTV refused, entry into Thailand for normal touristic purposes possible/ normal 30 or 60 days?

Hello,

a) used the search funtion, seems no one has yet found a Massage class working for the DTV?

b) Just in case, sometimes one does small mistakes or it's just chance: In case of DTV refused by a Thai embassy: is future (say.. 2 weeks later or 4 or 6 weeks after the initial DTV application) entry into Thailand for normal touristic purposes possible? Or could there be slightly negative consequences when opting for the normal visa on arrival for EU tourist?

Thanks!
