My business travel is all business. Company pays for it. Fully tax deductible. Might be different if it was not all business. If I was an individual or sole prop trying to get a bus. deduction, I would make sure 6hrs a day or more were really business. ...and well documented as business, in case of audit. Its not wise to mess around with your great uncle and his demands for tribute. My uncle did, and ended up losing his home, his cars, his business, his life savings. They did let him keep the shirt he was wearing.
