Is the Thai embassy in Phnom Penh reliable for obtaining a single entry tourist visa?

I would suggest staying in PP for an extra day or 3 just to make sure...look at it as an adventure

, NO thai consulate in S/E Asia offers same day service. The one in Phnom Penh offers 3 days service meaning you turn in your passport one day and get it back TWO days after that.

Vientiane, Savannakhet, Penang, Yangon, etc ALL run on a turn in your passport in the morning one day and pick it up in the afternoon the next day.

It cannot be done in 24 or 26 hours. :/

The shortest it can be is about 29 - 30 hours, and that'd be IF you're the first person to turn in your passport at 8:30 and the first person the next afternoon to pick up your passport at 1:00.
