Is the week in Bangkok and 5-6 days in Chiang Mai set in stone? I would modify and do Bangkok, Chiang Mai, Pai, and a Thai island. Can break down the number of days in each if interested.
7 days in Bangkok and 6 days in Chiang Mai is a lot compared to most people’s itineraries. Though I have done multiple months in each of those cities sos I understand slower travel. But for someone on vacation, 7 days is a lot in Bangkok. I would rather be able to do pai and an island.
