What should I put for the departure date and accommodation details when applying for a Non-O visa in Thailand?

The user is applying for a non O 90-day visa from Australia and is unsure about filling out the departure date and accommodation details. Comments from the community suggest leaving the departure date blank since it's a 90-day visa and recommending that a hotel stay of 2 to 3 weeks is adequate. Additionally, several users emphasize that it's acceptable to put short-term accommodation and that immigration will usually require formal notification only if renting in a business capacity.
