OKW- Largest and best laid out 1BR and 2BR villas (have full laundry room and full kitchen table, not the cramped booth the other resorts have). Quiet resort. Boat to Downtown Disney. Close to Epcot, so short bus ride. If you stay near the hospitality house (rent OKW points and book as close to 11 month window to get the hospitality booking which is a separate booking that goes fast...if you can't get hh booking you can request buildings near the hh booking section) you can avoid the many internal bus stops by taking hh bus to go out and getting off at Peninsular stop (1st stop) when coming in...IMO best resort for busing. They have a TS dining place, Olivias, but the CS place by the pool is limited in offerings. They take less points to book. If you drive, you can park right outside your building which is very convenient. Pool is okay with a so-so slide.
BWV- If you rent BWV points and can book close to 11 month window you may be able to get the lesser point costing standard view and save points. The rooms are small. The location is nice...can walk to Epcot and HS. Can also take boat but that can take a long time. The busing is not great from here to the parks as it stops at several other resorts. The parking is not great either and is a hike to your room. There are long long hallways here and your room could be at the end and a long painful walk after a day at the parks. There are tons of dining options with the BW and BC and the Swan/Dolphin nearby as well as having Epcot World Showcase right out your door. The international gateway is the best way to enter Epcot...so quick and easy. There is also lots going on around the resort at night. The pool is pretty cool if you don't mind clowns. This was our 1st DCV stay after we bought our points and my kids LOVED the pool that trip (they were 7, 7 and 9 then).
BCV- Much like BWV but a touch closer to Epcot (and a bit farther from HS). And it's a smaller quieter/quainter resort than BWV and so no long endless hallways. Parking and busing is similar as is dining options...though the marketplace store in BC does have a food counter for a decent CS (BWV has no CS). The pool is really nice but might be tough if you have really little ones (tough to keep an eye on them). This is my fave resort. Point cost is same as BWV- BW or garden view. The 2BR villas are better laid out and feel roomier than BWV (they have door to 2nd BR off the foyer where BWV has it right in the living room).
VWL- We only did 4 nights here back in 2008 so I don't recall too much but this resort didn't impress me...however my DH and DS say it's their fave. It has boat to MK. It is also, like BCV, BLT and AKV, a separate building from the main resort (WL). The DVC building seems very deserted and dark to me. It is very quiet and woodsy. The room was similar to BWV and smallish. There is CS and a couple TS places in the main lodge. The pool was really nice...both DVC and main pool...I think (just remember the kids liking the pool here). Point cost is a bit high here.
SSR- Our least fave resort. Smallest rooms. Lots of internal bus stops that you have to take (no trick like at OKW). Pool didn't impress us. We only stayed a couple nights here though. I remember waiting and waiting for the buses. It is convenient to Downtown (if you request Congress Park and can walk over, though that area is under construction right now)...but has plenty of dining options with Downtown nearby (CS and TS). Has CS and TS itself as well...and I really liked the CS here. Boat to Downtown as well. IMO, point costs for rooms are high considering the negatives here (it should be equal or less than OKW and they are a little higher than OKW).
BLT- Just stayed here. Good for families with stroller aged kids as they can be wheeled onto monorail. But we hated the monorail (packed, sometimes stopped, sometimes shut down, had to get off at TTC and switch monorails...etc). Short walk to MK is nice if you are a MK heavy tourer. Plenty dining options as you can monorail to various resorts and CP has CS and TS options. There is also TOTWL that offers some food (app type things) and you can watch Wishes from there. The rooms make great use of space but the studios are small. I think the 1BR and 2BR aren't bad but the point cost is high here. It is not a quiet resort (very open and all the cement/glass makes sound travel...and they pipe in music for Wishes and the magical water pageant thing) and the pool looked Meh to me...was just DH and I and we did enjoy the hot tub one morning. The CR pool was okay...we stayed at CR once and the kids did enjoy the pool even though it was January and chilly.
AKV- We haven't stayed here yet, but bought points here this year and have Christmas trip booked here. We have been there many times to eat and they have tons of great dining options, our fave signature and buffet are here (though might not be your type of food). It is a beautiful resort. When we 1st went to WDW, in 2003, and stayed off site I longed to stay on site at AKL someday (at a glance and on paper it was my dream resort out of all the WDW resorts...so we will see how it actually chalks up in Dec). My SIL owns here and loves it. She says the pools are amazing. They say the only negative is that it's far out from everything and the buses can be a problem. SIL loves the Kidani layout (1BR and 2BR) for the extra bathroom. This resort also has 2 pull-outs (sofa plus a chair) to sleep 5 in the 1BR (as does OKW and BLT) or 9 in the 2BR. You can have 5 in any 1BR, but you need to provide bedding and towels for the 5th person at SSR, BWV, VWL and BCV (like an airbed and blanket...which is what we did at BWV and SSR when we did 1BRs). I hear this resort offers a lot of things to do and could be a vacation in itself (like tours, talks, story time...etc.) and there's the animals. There are several views offered and you can get some low point cost rooms here with value (no extra bathroom in the 1BR and 2BR) or standard view. You can also get club level here but they get booked fast (as do value rooms).
