Sadly I have found that some resorts even resort to placing the notice in a pocket in the binder they give you. If I read your response correctly you said you "signed" a copy of the notice. That would tend to indicate it was included and would go a long way for the developer in defending any claim it was not included, but I may have misunderstood you. They don't have to make you aware of the right to rescind or show you the notice page and point it out in fact many time they hope that it is just buried under other papers and even if you signed it you were signing multiple documents and didn't read them. Clarify for me if they did actually include the notice as required by statute in your contract. I have copied the relevant section and will post it below.
NRS 119A.410 Right to cancel contract of sale.
1. The purchaser of a time share may cancel, by written notice, the contract of sale until midnight of the fifth calendar day following the date of execution of the contract. The contract of sale must include a statement of this right.
2. The right of cancellation may not be waived. Any attempt by the developer to obtain a waiver results in a contract which is voidable by the purchaser.
3. The notice of cancellation may be delivered personally to the developer, sent by certified mail, return receipt requested, or sent by express, priority or recognized overnight delivery service, with proof of service, to the business address of the developer.
4. The developer shall, within 20 days after receipt of the notice of cancellation, return all payments made by the purchaser.
