M&IE Expense - when to take?

[Stephen Race]

Hi, I stayed for 2 months at a rental property I own. I rented the property in 2013 - 230 days. For the 60 days I stayed at the property, I worked on it (more than 4 hrs / day) for 25 Monday thru Friday days, and had "Personal" or no work for 15 Monday they Friday days. Some weeks I worked on the property 2 days and some 4 days. So, question is can I take M&IE expense for the Weekend days? Or just for the weekends that I worked 3 or more days?
