What size villa will you have?
You may need to move some furniture slightly to make a parking spot for it near an outlet. I would suggest bringing an extension cord with you. That would allow you to bring the outer to the scooter.
Also, one thing to keep in mind is that the entrance to the Boardwalk lobby is on one level (that is where you would catch the bus to MK, AK and DD). The entrance to the boardwalk itself is down on level. It will be very important for you to know where all the elevators are. Other than that BW is very easy to get around. You can either take boats between BW, Epcot and the Studio or there is a very nice, wide walking path along the wate to both parks. Nice and scooter friendly whether you take the boats or walk.
