Before you part with the cash, I'd say it's definitely worth looking into renting DVC points. Weekend nights (Fridays and Saturdays) are more expensive, so if you could bear to make it a night other than your last, it would cost 98 points for a Grand Villa at that time of year. At $10-$12 a point, you'd be looking at $980 - $1176. It would be a good idea to get a DVC owner to check availability, though, before you go through the palaver of trying to rent points. With it being just one night and between "big" seasons, you could well be lucky, particularly if you're willing to be flexible about the date. If it really has to be your last night, it would be 146 points and, suddenly, that rate you've been quoted isn't looking too far off the mark.
