You can post your advertisements for renting your Holiday Inn Club timeshare at a few reputed timeshare trading websites. These websites are mostly visited by serious potential buyers and renters who are looking for good deals for timeshare vacations. Another good idea may be to post your ads on a few major travel-related online discussion forums or other sales or advertising websites. Craigslist is one such option to place your ad for free, and it can give you a wide exposure. Some timeshare owners place their ads on eBay, which charges an upfront fee. eBay is one of the largest e-commerce websites, which can increase your chances of renting your timeshare quickly.
