Making My Turnkey Provider Trip Tax Deductible

[Mark S.]

I've done a little reading on making trips/vacations tax deductible, but I'm still not totally clear. I am going to visit an out-of-state turnkey provider as part of my due diligence process to meet them and see their operation. They are about 6.5 hours away from me. I am leaving on a Thursday, driving 6.5 hours, and staying the night at a local AirBnB. On that Friday, I am meeting with the provider in the morning for several hours. When our meeting concludes, I will be checking out the town, staying over at the same AirBnB, and driving home that Saturday. I know there are some requirements on the number of hours of business activity, etc. I believe all my mileage is deductible. I want to confirm this and see whether meals and lodging are also deductible. I, of course, will save all receipts. Anyone want to take a stab at this?
