Looking for a rental this late in the season could be problematic.......But not impossible!
Over the years we've stayed in many of the upper, lower, and mid Cape locations. Our advice is to not lose too much sleep making this decision because from most locations you should be less than 40 minutes(depending on traffic) from anything you could want to do.
Because of this, we have always been drawn to the mid Cape areas of Chatham, Harwich, Orleans, Brewster etc. These locations offer so many activities and allow the quickest access to all Cape destinations.
We'll be there in August this year....can't wait!
