You will love the BWI.
Another option for breakfast is the Bellevue Lounge. You can see a menu here:

It's located off the lobby on the Inn side.
A favorite thing to do there is enjoy the night time entertainment they have on the BW. The kids love the BW games and getting icecream. We love to walk around the lake and visit the other resorts too.
When we stay at the BW we always walk to DHS and Epcot. We always make it there quicker than the boat!
The quiet pool at the resort is one of our favorites!
You can rent a surrey bike too. That's lots of fun.
If you haven't put a request in yet, ask for a room with an Epcot view. We had one there twice & it was awesome! We got to see the higher fieworks from Illuminations from our room!
