Joseph, 

There aren't too many differences between both since they are both used as our official test facilities.  You would be receiving the highest level of a Titleist fitting from our best Fitters at both locations.  The settings/conditions would be the same, assuming weather is cooperative.  Feel free to contact us at Team Titleist if you are thinking of booking a fitting at either location.

As someone from Massachusetts if you are planning to go to one of the facilities soon I suggest the oceanside one because it is cold here.
