I have to say I am a bit of a theme nut (so WDW in general is pretty much my favorite). Before my last trip in May I had no desire to stay at either BC or YC. In fact, of the two I'd have picked BC first. Then I booked Captain's Grille for my grandpa who loves anything nautical/lighthouses and after that ADR and seeing the YC...LOVE IT. The photos do not do the lobby justice. And, the theming I think is more dramatic so it still has some disney magic. As for location, BC and YC are right next to each other, connected with SAB. The difference in walking time is incredibly minimal. And, the boardwalk is maybe a 2 minute walk from there, maybe even less! You can see it right across the water. It is a separate hotel, but it is also a themed area with restos, bars, shops, and the bakery. They have performers and little food stands as well. You can walk through EP to the monorail, you would have to walk through UK and Canada and then you could take the side path over to the big fountain and past spaceship earth to the front. It will take longer though than a bus. I might suggest going to MK for a day via bus in the AM and then taking the monorail back to EP and walking through in the afternoon for a break, grab some food in WS on your way for lunch - since you have hoppers.
