If this is the week before or after Easter - Apr. 24th, it will be a strong rental. I think you can maximize the value by renting it yourself. If it were me, I would post rental Ads AND private exchange Ads for this week - maybe a DVC owner would liked to come to CA for Spring Break.
If you let the resort rent it for you, I am sure they will take a big chunk.
Joining RCI again is going to be expensive, and holiday weeks are difficult exchanges to get.

There is also a list of resale websites at the top of the Buying, Selling, Renting, board that you may want to take a look at.
Many people don't like Craigslist, because you get a lot of scammers who respond, but they are painfully obvious, and I just ignore them. Another tool I use to eliminate the scammers is that I only accept payment by Paypal which requires a verified bank account or credit card to be registered. I just rented my Hawaii timeshare for full asking price on Craigs list. On Craigslist, you need to create a Craigslist Acct., create 2 different Ads with different titles and wording, and rotate them every 3 days. You don't have to rewrite the Ads - if you create an Acct. they will be saved in your Acct. and you can just report them.
I also have my own webpage at
www.freewebs.com that I've had since 2005 with lots of pictures, info., and recommendations, and I think that helps because it shows that I'm reputable and well-established.
