I don't think it differs from the incentive offered to non-Marriott owners. Each property has slightly different incentives. There is always an option to get MR points, usually 10,000 or 15,000, although they have been offering 20,000 recently at Oceana Palms. Often an option is to get gift cards or certificates to use at restaurants or retailers. They now also frequently offer some one-time use DC points as an incentive. Where would the OP be sitting through a sales presentation?
