Thanks, from a former resident of your hometown, tiny Pine Bush, NY!
I haven't tried Homeaway. Anyone else have an opinion on them?
I have had good results with Redweek, and have also rented some weeks through the TUG marketplace. The TUG last-minute rental board is very good if you are willing to accept $100 a night or less.
I use eBay only for last-minute weeks that will sit empty, because prices are very low there. Also, listing on eBay can be a huge hassle. One needs to be "travel verified" and eBay has serious bugs in their travel verification system. You might be verified in an hour, or it might take a month. I had a last-minute week that I wanted to list there. My travel verification had expired, and eBay never notified me of that. I didn't find out until I tried to list my rental there and was denied. Despite repeated phone calls, emails, and a fax, it took eBay about three weeks to give me travel verification, and in that time, the check-in date had passed.
One thing that
is nice about eBay -- they have a program, called "Giving Works," where sellers can list an item with some or all of the proceeds going to a charity of the seller's choice. (eBay actually bills the seller's PayPal account for the charity contribution, so it's not like a seller can say they're going to give the money to charity, and then just weasel out of it.) A couple of times when I've had exchanges I couldn't use, I have listed them on eBay with all proceeds going to charity. There are many charities the seller can choose. I like Doctors Without Borders, who won the Nobel Peace Prize for saving refugees and other victims of wars.
Craigslist is good for many areas of the country, but they used to (and maybe still do) have a terrible problem with their Orlando listings. If a timeshare owner listed their timeshare there, landlords at competing full-ownership condos would report the listing as violating Craigslist rules, and then Craigslist software would automatically remove the listing. I had listings that got flagged and removed in minutes. When I asked for help on Craigslist's forums, I was called obscene names.

Several other TUG members had the exact same experience, obscene names and all.
I'd like to use Craigslist for my Orlando timeshare, but I don't want to be (falsely) flagged for rule violations. I want to keep my Craigslist in good standing. Anyone have recent experience using Craigslist for Orlando?
