Since you're from Michigan and the kids will be taking their 2-week vacation with you, I'd highly suggest Gulf State Park, Gulf Shores, Alabama.
That was the first place that popped into my head, also! True Road Warriors can make that drive in one long day from lower Michigan if need be. The only drawback is that depending on the weather, it can be cold enough to need to winterize if one has unheated tanks (that was our experience when we stayed there in 2013). The sites are incredibly huge, the facilities are top-notch; and Gulf Shores has all the fun attractions, too.
