Your idea to visit a few resorts is a great one. While
Marionnette is correct in saying there's a difference between visiting and staying at a resort, at least by visiting you'll have a sense of what to expect, and in some cases, the very theming (or lack of) could make a difference in your choice. Also, keep in mind that doing a ton of research into
DVC is also a good notion: direct vs. resale, length of contracts, Use Year, dues, availability during various times of year, et. al., are just a few of the intricacies to mull over before you jump in the pool, so to speak. With that in mind, here are a few thoughts regarding your initial question.
SSR - Definitely a good one to visit. While the convenience to Disney Springs is wonderful, many do not like the sprawling feel of it nor the theme. Also, you can arrange to look at a model of Copper Creek while you're there as they have models. I believe they should also have the new Riviera as a model, too. . .and you can get free ice cream and perhaps a few FPs.
BWV/BCV - These two are close to each other so you can check out both. What I'm about to say is heresy, but for me, the two resorts are darn near interchangeable. I prefer BCV due to the pool. BWV used to have a model room you could tour, but I'm not sure it's open anymore.
BLT - Due to its proximity to MK, you'll definitely want to take a look here. Further, it has a sleeker, more modern appearance than the other resorts, and some don't like that vibe at all.
As for the other resorts, here's why I didn't choose them.
VGF - Very nice, very upscale, but very expensive to purchase, and the
point charts are among the most onerous.
OKW - The largest rooms on property, but it's somewhat similar theming to SSR, and you can't walk to Disney Springs.
BRV - My home resort (though I will always call it VWL), and while I love it, Copper Creek is newer, and all the amenities at the resort are the same for both DVC properties. So, if you tour a model of Copper Creek, though they look different than VWL rooms, you would get a longer contract.
Poly - The lack of 1BRs makes this a no go for us. You either have studios available or very expensive bungalows. I wouldn't prefer to own at a resort that doesn't have 1BRs since we appreciate that extra space.
AKL - Well, you'll already be there. FWIW, that resort was designed by Peter Dominick who was also the architect for the Wilderness Lodge, so they share some similarities in scope and the wow factor.
Have fun!
