We've stayed at 4 of the properties so far, and the only one I have no honest desire to stay at is OKW, but will be staying at BCV for the first time in September. Of the four I've tried ranking is as follows:
1) AKV: Love everything about this resort from theming and views to the smell and food options. Also love the dedicated bus service. Nothing I hate so much as sharing buses with another resort.
2) SSR: Love the theming here, the decorations, the proximity to Downtown Disney, and once again not shared buses. Though with all the stops it sometimes feels like they are which is why I always stay in Grandstand.
3) WLV: Great proximity to MK, beautiful theming, relaxing setting, good restaurants. But the shared buses for the other parks I hated.
4) BWV: Great location, walking distance to Epcot, boat ride to DHS. Shared buses a problem, as is the creepy clown pool. What were they thinking?
