Great questions........
We have 10 Marriott weeks (most bought between 1998-2005)......8 weeks at Hilton Head, one at Myrtle Beach & one lockoff at Williamsburg, VA),
..........................................................................................................but we also own 6 non-Marriotts for various reasons, bought between 2005-2015......
..........................................................................................................a few early Marriotts bought directly, but many resales. Non-Marriotts all resales.
+ Two non-Marriotts (Waterside by Spinnaker 3BR/3bath) are at Hilton Head also, strictly for extra HH time.....(usually give one to my office manager & family).
+ Two non-Marriotts (Sheraton Broadway Resort-Vistana) at Myrtle Beach for extra Myrtle Beach time (and I give those to a couple of my other staff members).
+ Two non-Marriotts (Church Street Inn-Festiva) in the historic district of Charleston, SC......just because we love Charleston. (We split those 2 weeks into 4 annual weekend stays.)
WHY?
Flexibility, access to locations we love, access to seasons we enjoy, access to activities we like........not only for my wife and me, but for the children (and now grandchildren).
We also have weeks for trading......we use Interval Int'l to obtain 2-3 amazing trades annually.....we've visited many, many different resorts around the USA and in Europe.
(Newport Coast Villas, Boston's Custom House, Summit Watch & Mountainside (all skiing), Ocean Pointe, Lakeshore Reserve, Cypress Harbour, Grande Vista, Royal Palms,
Maui Ocean Club, Kaua'i Beach Club, Beachplace Towers, Manor Club (original), back into Grande Ocean, back into Barony Beach Club, Surfwatch,
Harbour Club, Harbour Point, Sunset Pointe, Monarch, back into Oceanwatch, Marbella Beach Resort, Cameron House (Loch Lomond, Scotland),
Wychnor Park CC (central England).
We have visited several of the above resorts multiple times thru trades (in addition to our ownership weeks at a few)........upgrade of seasons, for example.
.........into Boston Custom House 10 times, into Orlando resorts at least 25 times,
Summit Watch x3, Mountainside x3, into Hilton Head resorts 35-40 times, into Oceanwatch 5 times, back into Manor Club at Ford's Colony (original) about 10 times.
We have been extremely flexible with our ownership weeks as to where we can go, and therefore have pretty much been anywhere, anytime.
And being enrolled on many of our Marriott weeks, we've used Destination Points annually too. Very lucky.
Never bought Trust points directly from Marriott, only enrolled several weeks in 2010......enough to have about 20,000 annually if we wanted to (but we don't, not yet anyway).
I'd say we were simply in the right place at the right time.....pure dumb luck. All our ownership resorts are winners, and that makes the difference.
Couldn't be happier.
