My experience with VRBO for many years with baseball, East Cobb included, was I would pay for a week which saved money, but I usually left a day early. Yes, it had a kitchen, but still ate out a lot. At his college tournament in Charleston, SC, when son's team was eliminated, I refused to leave early from our lovely VRBO.....Charleston is such a nice town, so we just hung around and played tourist. BUT, with pro ball, you never know when or where you player will be so I find hotels MUCH more convenient to cancel and change. I will not stay in a VRBO for baseball now due to the inflexibility and the additional fees. If you stay with several families and make it a vacation, that is different.
Get a hotel credit card and rack up some points.
