Not a fan of the Swan except for it's location.
We stayed at BC last December and had a few meals at the nearby Swolphin restaurants (not the high end ones, but moderately priced sit down places). There was a noticeable difference in service at each of them compared to our "worse" WDW restaurant...and it wasn't for the better. Food was just ok, but service was hugely indifferent at best and absent altogether at worst. I even complained to a manager, and as a former waitress I am usually very reasonable and understanding when it comes to wait staff issues.
I'm also not a fan of the hotel 'theming', which is very nondescript inside, very generic chain Hilton or Doubletree interior (based on a previous short overnight stay). I just don't find the Swolphin to be Disney Magic.
So in short despite the location, I do not find the Swan or dolphin to be a good value for my family. I would much rather stay at a moderate with a bus ride then stay at a non-Disney property, even if those are within walking distance to two parks. I have stayed at numerous moderate options at Disney, and I have been impressed with food options and service overall, room decor, and inside and outside resort theming every time.
Those things mean so much more to me than location. And as I have never had an issue with bus transportation from any level of resort at Disney, I would be thrilled to stay at a Disney moderate resorts ever swan or dolphin.
