>> I want to rent a week from someone on Redweek who doesn't own at the resort but owns elsewhere and will be exchanging for the week. I have read this isn't o.k. through RCI, but it is a Marriott Resort posted through Redweek.<< =================================================
Rendering no judgement, I can still tell you this much with some certainty:
1. It is against both RCI and II rules of membership to rent out for profit any week obtained by "exchange". Period. Where that week might then get advertised for (improper) rental is irrelevant.
2. A person attempting to rent out a week which they obtained by exchange through either RCI or II might, if subsequently discovered by the exchange company, have their II or RCI membership terminated.
3. Worst of all, if you rent an exchanged week from someone and that rental is subsequently discovered by RCI or II at or before you check-in, in addtion to #2. mentioned above the reservation involved can be outright cancelled by the exchange company, leaving you with no place to stay and then also having to chase after the "landlord" for the money you paid them for the prohibited rental (...good luck with that).
Re: >> The exchanger has told me they will give us a guest certificate with the reservation number on it. I was told the week is held under Interval International, which I don't know what that is, and they will add my name once the reservation is complete.<<
Interval International is an exchange company, just like RCI, except smaller. And just like RCI, as previously mentioned, II prohibits the rental for profit of an exchanged week. Period.
You and the exchanger improperly renting out an exchange MIGHT get away with this, but my recommendation would be to instead look for a more legitimate, risk free rental from someone who actually OWNS what they are renting out to you and is prepared to PROVE that fact to you. Otherwise, as itemized above, there are risks involved for both you and the person attempting to rent out an exchanged week, in clear violation of II rules and terms and conditions of membership. Ultimately, it's your decision to make...
