I know in Laos and KL you need an appointment to get a tourist visa, but what is the situation at Khota Bharu? Do you need an appointment there, I don't want the same thing that happened to me in Laos where I didn't know I needed one, but I cant find it anywhere online while searching.
TLDR : Answer Summary
At the Thai consulate in Kota Bharu, you do not need an appointment to apply for a tourist visa; it operates on a walk-up basis. However, be aware of their unusual opening hours, which are Sunday to Thursday.
