So we in essence need 4 hours of commute time plus time at the airport...so probably should give ourselves 6 hrs or so...I initially thought it was like 2.5-3 hours from Sheraton Hua Hin to BKK

What do I know.
IMO 6hrs is safe for international flight due to immigration on BKK
for distance at the end/begining of expressway (Rama II road)
to Sheraton hua hin 170 km
to BKK airport 46 km
total distance 216+ km
