I think dtsm meant regular price one way from the airport to hotel with the return trip from hotel to airport at 50% discount if you purchase a roundtrip at the same time, not THB 550 for the round trip.

There are AOL limo counters in the baggage reclaim area, before custom and excise inspection. Big sign, cannot miss them.

I personally agree that it's a much better arrangement than taxi.

If you really want to be pampered as you're on your honeymoon, you can always book Fasttrack to meet and greet you on arrival to expedite you through formalities. Congratulations!
