Whats your budget ???????? hard to sell you a hotel room, without that info.
As the other BM's state, between 1.30 hours to 2 hours...depending on traffic.
Have not tried it from the new airport to patts.
A stay in the Sugar Hut...thats good and classy.but if your on a tight budget...there are nicer hotels in the area.
Welcome To Sugar Hut Resort - Pattaya City Jomtien Road - Thailand
But again use the search function or this.
Thailand Hotels and Resorts, Pattaya.
Enjoy.
