I am planning to take a bus or train from Chiang Mai to Phitsanulok on Feb. 10 or 11th. Will there be a lot of people travelling at this time? Should I buy a ticket a few days in advance because of this possibility?
Will it affect other places I'm travelling in the Isan region - Loei, Chiang Khan, Nong Khai, etc. re availability of seats on buses, trains?
