Another smooth entry data point:
Arrived at BKK from LAX (via Manila) after being away for 2.5 months. This was my second entry on DTV and the first time flying in on DTV. I have a pretty extensive visa history - almost 9 years of continuous stay on visa exempts, tourist visas, and non-o visas.
I expected to be asked a few questions, but nope - stamped right in!
Facebook in its great wisdom isn't letting me comment on this post, so I'll answer questions here:
* No, I didn't need to present any document since my visa is the old kind - a sticker in my passport.
