Getting to Longji Rice Terraces in mid-November

How difficult is it to get a private car (no bus) from Guilin city (not the airport) to Longji rice terraces on Nov 11, and then come back in a private car (no bus) on Nov 12. I've heard that sometimes if the bus driver doesn't feel like driving on the trip back from Longji to Guilin during low season, you're stranded. In this case, what other methods of transportation are available?

I was trying to set this transportation up with my innkeeper, but he refuses to reply to my inquiries. I hate to not go to Longji, since I have 10 days to see Guilin and its surrounding areas, but I'm about to cancel this portion of my trip, because of these transportation issues not being resolved. Any information that anyone can provide will be greatly appreciated.
