Unless you love your scooter or it has special rarities, why not just sell it and buy one here - it is probably much cheaper for a second hand one anyway.
Got a similar conundrum - was going to drive my baby (as in small) 125 Honda to the north of England. I reckon I could just as easily buy another one there for about the same price as the hassle. (on a good day with Easyjet).
Rental car for a week and a bit vs a half ok bike - probably about the same.
My tank of my honda only holds enough for 120 KM - not really worth the hassle. ferry, hotels etc.
i suppose if you had time, then it is no issue - but we do not get so many holidays here in CH.
