DPS is getting better, it was so bad in 2007, a hour wait was the norm, but went through last week in 5 minutes, mid afternoon around 2ish and friends advise that the time to avoid is the JAL arrival which clogs up the system, as many of the paxs do not have the US$10 or US$25 for visas. If there are two of you travelling, arrange for one to line up with the passports with the hand luggage whilst the other pays for the visas and gets the receipts. Worked for us when last year when it was bad, I had to loudly advise there was a crowd in the toilet when I tried to enter the passport line though. regards bkkrop
