If you just want to check out the MVC properties themselves to get a feel for them, Ocean Watch in Myrtle Beach and the "Big 3" within Hilton Head are all nice. If you stayed on HHI, you could always drop by several MVC resorts to walk through them to get a feel. There are so many MVC resorts on HHI. Within MB, there is only one MVC.
On HHI, if you are open to a non "Big 3" on HHI....this might be a good time period to stay within Sea Pines, visit Harbor Town, Lighthouse, etc.....at say Monarch, Harbour Club, Harbour Pointe, Heritage Club, etc. While I personally have not stayed at these, they are in a nice location for a couple day stay outside of prime beach season. And, likely cheaper to boot.
Good points, and of those "non-big 3" I like
Harbour Club the best (layout and views), followed closely by
Harbour Point (views), then
Monarch (with caveat). Altho Monarch is oceanfront, the units (total space and all individual rooms) are extremely small, with two twin beds in 2nd BR (unless you are only a couple, which makes it doable). Personally I don't care for Monarch because we feel very claustrophobic, and the units are very dated and tired, some of the chairs are falling apart, but I list it only because others seem to be wowed by the oceanfront location.
Harbour Club has a very nice layout, is spacious, and has gorgeous inland waterway views, which I happen to like just as much as ocean views. From HC, you can walk to Harbour Town shops and restaurants too. If possible, get a high floor for best views....most are somewhat obstructed, but some high floor views are great.
Harbour Point in Shelter Cove also has wonderful waterway views, the best actually, if you're lucky enough to get one of them!!!! (They do have more waterway views than the other resorts, Harbour Club & Sunset Pointe.) Request high floor and best waterway view available.
(Sunset Pointe units are set back behind Harbour Point units and don't have the best views, but the units are equally nice.)
Destination Points requirements at HP are very minimal, best deal around.
(Harbour Point lowest, Sunset Pointe next, Monarch highest of "non-big 3",
BUT all are still well below the "big 3" of Grande Ocean, Barony, and SurfWatch.)
