You'll hear all kinds of thoughts and opinions from these boards, but here is my 2 cents as someone who lives in the State of Georgia, and who prefers to drive to desirable locations, has two preteen boys, and like Beaches and Amusement and Water Parks.
It's about how you equate value, when you need to go. I know you are interested in Great Smokies but there are several good resorts within Wyndham that you or perhaps your family may want to go to.
I'd first research where you would want to go and get a good feel for the point cost you might need studying the point charts and looking hard on On Peak Vs Off Peak Times then maybe ask the kind people here if ARP is needed for when you want to go do your preferred locations AND IN YOUR PREFERRED ROOM SIZE. Some desirable locations have low maintenance fee contracts (which is a win win for ARP and low maintenance fees) and some locations have different maintenance fee contract pricing (Ocean Boulevard Comes to Mind having some low fee and high fee contracts).
I Pay a Premium on maintenance for owning at Bonnet Creek but I want Presidential Suites at On Peak Travel Times (including Christmas). Also for some reason Thanksgiving Week is in the "Value Season" for Bonnet Creek (almost half the point cost of Christmas stays), so to my family that is a good value to stay in large presidential suites at Thanksgiving (and even booking multiple rooms for family) given the cost to stay anywhere close to that location during Thanksgiving. That said you can book deluxe rooms at bonnet Creek Thanksgiving week 10 months out with a low maintenance fee contract, but I want Presidential Rooms and pay a premium to have a better shot at getting them 13 months out.
There are some interesting things out there like the Myrtle Beach Resorts...owning at one gives you ARP to ALL with maybe some exceptions. So I picked up a low maintenance fee OB contract that gives me ARP to all Myrtle Beach Resorts but am happy to spend those points elsewhere, but I like having ARP at multiple resorts.
I own at Clearwater because I want 2 BR Presidential Rooms Spring Break Week and book it 13 months out.
I prefer own where I want to stay and travel at on peak times as my wife is a teacher and my kids are in school. I generally get what I want when I want it but have to plan 13 months out, but I enjoy that planning process. I own contracts at describable locations that should be unload able if I need to unload them.
If I had more flexibility and didn't care for the presidential suites I'd look hard at the lowest maintenance fee contracts out there for Wyndham, or if I were on a more limited budget I'd network with VIP's and rent from them at a desirable location to see what it is like and if you want to own there.
