My husband and I have a Marriott Maui Ocean Club ownership. It's a Platinum, Ocean-View unit and we love it. We get to visit Hawaii once a year if we choose to or any Marriott Resort worldwide! Even in places that Marriott doesn't have resort-type accommodations, we are able to use the Marriott hotels, which are all over the globe. Also, we researched a lot prior to buying and have found out that that the resale value of Marriott is among the best when it come to timeshare.
I remember looking into WorldMark ownership because of the great number of locations they offer, but Marriott was a better fit for us.
