Mixing vacation rental and personal use?

[Luke Monahan]

I was talking through a Dario with a friend and I was hoping for some feedback. 

Let’s say I have $100,000 to put down and I want a beach from property; East coast. Can I get enough occupancy with a property management company to break even, with a week of summer personal use?

Or should I put 100,000 in a safe investment. And spend ~$4000 on the vacation from investment  interest. 

Furthermore is it bad business to mix in personal use.
