Which ones ended up "meh"?
Unless you're just curious, the answer won't necessarily help you make your choice at all. What someone else thinks, "meh" factor, doesn't actually mean squat for anyone else unless it's someone you know well and often agree with on the aesthetics/niceties.
I really think the emotional impact can almost count more than non-financial considerations like location or spaciousness. That is--Does the resort have "feel-appeal" TO YOU?
If you're pretty familiar with what areas of WDW give you a good feeling, then I think you can probably tell from a video if a particular resort does, too.
Does anyone have any recommended videos for any of the
DVC properties?
We find the WDW News Today ones with Tom Corless much more objective than other tour guides whose videos we've watched. Corless resembles Pete in that he won't hold back on telling you exactly what he doesn't like and why. He looks carefully for odd layouts, defects and needed repairs and points those out, mentioning if the resort is scheduled for refurb/reno soon so you know when things are likely to improve. If he likes the villa, you'll certainly get that, again for practical reasons like spaciousness, layout, lighting, etc.
Paging Mr. Morrow's tours are pretty good for the practicalities, but he's so chatty and gushy he drives me bonkers.
The others, IMO, have annoying little quirks like pointing out Hidden Mickeys everywhere or are too promotional.
