Having used "Sky Auction" to make many travel plans, a few destination had me staying at places that offered Time Sharing. Beautiful, well constructed, well placed but often when I signed in, they TRIED to corner me into attending conferences, meetings, breakfasts whatever to interest me/mine in the idea of a time sharing. Time Sharing was very popular in the eighties and nineties and lost speed and interest. Now, if you are lucky you can pick up weeks for a song!! They just are not in favor anymore. Couple that with annoying interruptions to your vacation time, high pressured sales and the inability to sell your week/weeks if desired, it can be a nightmare.
Often, people go to festivals or affairs and sign up to win something, only to start getting pelted by time sharing offers in the mail or by phone. A quick way to get rid of these pesky callers is to tell them you are filing bankrupcy, that you don't meet the minimum salary requirements, or that you are on Social Security! One of my young neighbors up the street went on a timesharing vacation offer and spent four hours each day being drilled and grilled! Not my idea of a vacation, but, if it works for other people, and they can get a nice outing for free why not? Like Digriz says stay strong, be firm, and close your ears to them as they pressure you. Don't do anything you will regret a year from now.
