Hi gary,
I am an HGVC owner (as well as a SSR owner), you may want to reference
http://www.tug2.net for more information on HGVC. I am looking to use the strengths of both programs apporiately.
I have kids and want to travel in winter months, so I am going to be held to traveling during school breaks. A good strategy may be to use
DVC in October/February, HGVC in November (thanksgiving)/April for most years (although I have the itch to go to SSR next turkey day).
