How do we handle a trip that had both personal and business travel? I was planning to account for the accommodation in the cities where business was conducted and per diems there, but not on the cities with no business purpose. If we stayed longer than necessary in the 'business cities", do we need to use some proportion for the housing/per diem (i.e. 5/9 of the days were business, so deduct a percentage)?
In addition, we had travel insurance and rental vehicle costs. Should that also be prorated (insurance required purchase for entire duration, not just for days on business)?
