I may need to drive from Jomtien to Korat city in the near future. Google maps suggests Rt-7 to Rt-304. While that is clearly the faster route it is also traffic and truck intensive.
Is Rt-331 to Rt-304 a reasonable alternative? I know longer and twistier but less traffic intensive and more scenic?
I won't be in a hurry and may actually make it a two day trip, staying a night along he way.
