My flight is arriving at bkk airport at 12:00 pm on April 13th, I have a doctors appoint at bangkok hospital pattaya at 3:30 pm. I will be able to use the fast track immigration lane at bkk and wont be checking any luggage so my arrival at bkk should go pretty smooth my question is will i have enough time to make my 3:30 pm doctor's appointment if I catch a taxi at bkk and go straight to bangkok hospital pattaya, the reason im asking is due to songkran and traffic issues
