Coming New Year's Day, a new ferry service to transport you to and from the two popular destinations - Pattaya and Hua Hin.
Come January you'll be able to catch a ferry from Pattaya's Bali Hai pier to Hua Hin's Saphan Pla and will take you around one and a half hours in total. This journey across the Gulf of Thailand will shave three and a half hours off the only other transportation option available to-date, via road.
Considering the distance, there THB 1,200 costs being charged by Royal Passenger Liner Co. isn't too pricey. If you don't fancy paying this, you'll be able to catch a free trial for two or three days in December.
