What is the process for applying for a Thai visa from Bali without a hotel booking?

Hey - was wondering if anyone has advice on applying from Bali, since I have a free place to stay (also not sure about the document requiring proof of location, would have the Visa on Arrival but not hotel booking). Was told you could apply online from there, but also there was a chance that you might be called for an interview, in which you would have to fly to Jakarta. So was just wondering if I should take the safe route and just fly to Jakarta or if there was a good chance of having no issues applying from Bali.

Thanks
