Resort expiration dates, January 31: BWV 2042 (same for BRV and BCV if considering those); AKV 2057, CCV 2068.
BWV is my favorite resort that I bought in the 1990s but I would not advise any young family today to buy there for three reasons: (a) its expiration date is way too soon for a young family and you should assume Disney will not be extending the date for existing owners; (b) its new and resale prices are too high if getting only a 2042 end date; and (c) it has a serious 11-month reservation issue (meaning you can have problems getting a room even at 11-months out) for standard studios and 2BRs year round and boardwalk view studios and 2BRs during the high demand "Fall" season (late Sep to marathon weekend in Jan), and the problem just keeps getting a little worse every year.
CCV is in an excellent Wilderness Lodge Resort, has that very late expiration date, points needed for studios to 2BRs are similar to BWV, new and resale prices are quite high but perhaps not prohibitive, and rooms, though somewhat smaller than elsewhere, are fine. But I would still highly recommend against purchasing it. The studios (and 2BR lock-offs) have developed an 11-month issue similar to BWV standard view studios and 2BRs. Added to that is that there have even been times in the fall season when 1BRs and dedicated 2BRs have disappeared right at 8 a.m. at 11-months out. The cause of the problem is Disney's adding to the resort a lot of point-excessive cabins that few can afford to buy the points for, but they gave DVD the ability to sell a huge amount of extra points to those who purchased only enough points to get studios and or other rooms. In essence, if you buy CCV, you should expect to have disappointment at times in getting the room you want even when trying to reserve at exactly 8 a.m. at 11-months out.
AKV, with the good 2057 end date, is an outstanding and unique resort with the African savanna theme, animals in the savannas, and very good restaurants and pools, including a water playground area free the kids at Kidani. Jambo rooms are comparable in size to BWV as are the Kidani studios. But the Kidani 1BRs and 2BRs are ideal, both significantly larger than BWV or CCV, and with an extra bathroom (three in the 2BR,and two in the 1BR). The living rooms of the 1BRs and 2BRs at both Jambo (other than value rooms) and Kidani have the twin-size pull-out sleeper chair in the living room, which does not exist at CCV, BWV (or BCV and BRV). It's new and resale prices are less than BWV or CCV. If Were a young family today choosing among AKV, BWV and CCV, AKV would win by a large margin. AKV has its own 11-month issue for the small number of value and club level rooms but no threat to develop one for any other rooms and one should not purchase AKV just to be able to get value or club level rooms.
