Actually, Pattaya is CLOSER to the brand new Bangkok International Airport.... than Bangkok is... driving time wise.

Also, Pattaya in on the beach.  It has gorgeous resort hotels like The Ritz Carleton or the Four Seasons --- on the beach --- to choose from.... for the Conference.

Bangkok is a big ugly dirty city.    Trust me.    Everyone would like the places on the beach in Pattaya better than anywhere in Bangkok.

It amazes me at how critical people can be.... about places they've never been to... and things they've never attended... etc.

Anyway, you'll love the 5-star resorts on the beaches of Pattaya....  for about maybe 10% of the cost of the same room in the US.

Oh, and the last time I was there....   The hotel sends a Mercedes limo and driver to the airport to pick you up... no extra charge.

Speak of what you know.
