Anyone combine business trips with personal trips?

[Andy Basler]

Hello group,

As I grow my business and become more in love with Rentals, I thought about looking at other markets in areas that I also like to visit.  I assume I can count these trips as business trips if I have the proper documentation showing what I've done at that location, and only the portion of the trip (transportation and lodging being the biggest) can be counted towards the business expense.

Not asking for tax advice per se, just curious if others do this or any personal experience. 

thanks in advance
