In the event that you have had a bad experience on holiday, a consumer can quite easily stop going to that holiday destination or not deal with that holiday company. In this business model, the holiday provider company succeeds or fails based upon the quality of service and experience enjoyed by the consumer. In timeshare, you are bound to that resort and as such, and if you do have a bad experience, the contract you signed reduces the effect of those holiday issues. In short, you cannot leave and the issue you might have (even though important to you) are not terms which could void the contract you signed.
Of course you could choose to exchange you timeshare resort and enter a system of exchange. This would get you away from the holiday resort. However, you will still have to continue to pay the fees they are contractually allowed to charge you. In some circles it’s called the “lock in”.
Saying this, if you are obliged to take holidays at certain times of the year, timeshare might be your saviour and you might have a propensity to forgive minor misdemeanours as your holiday and vacations are safe and secure.
