Thank you. As of now my plan is to apply online for a tourist visa and upon arrival at the temple in Chiang Mai, they will help me to change it to an ED. I am looking into arriving by boat and from what little i could find online on the subject, it doesn't seem that arriving by water would be a problem. Also, regarding the Test and Go, it seems I'll need to pre-book a hotel the first night at the point of entry and again, presumably in Chiang Mai, on day 5. If there's anything I may be missing, any respectful and constructive advice would be appreciated.
