Arriving Don Muang early afternoon and leaving Suvarnabhumi early next morning I wish to travel to Pattaya and back.

Since taking two taxis to/from a Bangkok hotel will cost me at least 500B I figured I could enjoy the night in Pattaya equally.

I know I can get a bus at Moh Chit, but finding transportation to Suvarnbhumi out of Pattaya around 5am might be problematic (need to check in around 7am, flight leaves at 9am). I do know I can book a driver similar to Mr.T to drive me to the airport, but I think finding someone to pick me up Dong Muang and delivering me Suvarnabhumi next morning to be a better solution. I doubt a returning taxi can be booked around 5am and the Bell bus leaves at 6am, with an arrival time not earlier than 7.30 it seems risky to check in on time.

Telephone number or email of trusted driver to book is welcome,

Thanks

The four hours spent traveling to and and from Pattaya could be better used by staying in Bangkok.

Agreed, but I find Bangkok rather boring (coming from an Issan village)

If you have a friend here in Pattaya with 24 hour notice he can book taxi to airport for B800-850 plus tolls. I have had reliable pick up at 4am and 5am.
