Does anyone know the bus schedule from Sukhothai to Chiang Mai? Also are there first, second, and normal bus classes? Are any of the buses air conditioned?

Thanks

If you are staying in Sukhothai the Sukhothai bus station is just outside town you can check there there are sooooo! many and has buses going to Chiangmay at all times, we went from Maung Kao where we stayed and there were three or more air-con buses a day from the village by two different companies. Morning , afternoon and evening.
