Although the topic here deals with energy conservation, the larger theme is the cost of energy. Take that one step further and we're worried about the US economy and how it impacts us personally. So the issue is discretionary spending and timeshares are very near the top of the list.
We all have rationalized the initial purchase, and then every year why the maintenance fees are a "good value for the buck". I suggest many of us did not spend much time considering the travel costs. In January 2001, the price of gas was $1.46 and today it's about 300% higher. Airline ticket pricing is just starting to escalate and it won't be long before that too is outrageous (and unaffordable). Travel costs are now a huge issue.
So all this is a real paradim shift from
economical vacations to serious questions about
affording those vacations and
"what to do with these timeshares". If it were not for the fact that other costs such as food, healthcare, etc are still very cheap, it might start to be like real money.

Maybe I need to go out and fertilize my forest of money trees!
