No offense to Dean but his comment about flexibilty is not accurate. There is a connection between the Marriott Rewards program and MVCI. Every other year, Marriott owners who purchased their interests from Marriott can exchange their week for Marriott Rewards points. The number of points is determined by the season and size of unit purchased (in our case, owners of a Sport Week at Cypress Harbour, it is 90,000 points.) Those points can then be used with any other points accumulated for stays at an Marriott, Rennaisance or Ritz-Carlton in accordance with the Rewards Program. This option is not available to a purchaser of a resale (unless the purchase was handled by MVCI resales.) In addition, an owner of any Florida Marriott property built after Cypress Harbour (Grande Vista, Ocean Pointe, BeachPlace, Villas at Doral and the new one in Panama City Beach) has an added benefit. He or she does not have to go through Interval International to book a stay at one of the sister-properties. It can be done directly through Marriott. I am not aware of any new Marriott properties selling fixed-weeks (there may be one, I'm just not aware of it and very familiar with MVCI.) It is my understanding you can only buy into a "season." The seasons are essentially based on popularity of the resort destination. For example, our Sport Season (which was the mid-priced season of the three seasons available when we bought) generally runs from May 1 to June 20 and August 20 to December 20 (the exact dates change each year but are usually within a couple of days.) If you want to get a unit outside of your season in Orlando, it must be done through II (which is generally fairly easy as the 3BR unit I referred to in my first post was in July.) At newer resorts, the seasons are named for precious metals (bronze, silver, gold and platinum.) And as for Joe Black's comment about owning both, that would be "Timeshare Nirvana."
