Just a tip for when you are staying at BWV...when you go to MK area resorts for dinner (Cali Grill, Artist Point), remember that in order to take the monorail to MK from Epcot, you have to walk to Epcot or take the boat there, enter through the International Gateway (World Showcase area, between France and UK), walk all the way to the front of the park, exit the park and then take the monorail. The easier thing to do is take the MK bus and then walk to the Contemporary, or take the boat to Wilderness Lodge. As an alternative, you could walk or take the boat to DHS and then take the appropriate resort bus from there, but that would take longer for MK area resorts in my opinion.
Another tip...if you are up for walking, it only took us 12 minutes to walk from our room at BWV (standard view across from the bus stop) to the entrance of DHS, and that was walking with a 5- and 7-year-old. The boat first stops at BC/YC, then at S/D, and then goes to DHS. It does the reverse on the way back from DHS. We took the boat back one day and just got off ay S/D and walked because it was taking so long and we still had 2 stops to go! The good thing is that for Epcot, it is a straight ride from BWV and back to BWV! But we just walked. We only took the boat once because it happened to be right there when we exited the park.
You have some great restaurants planned! The day you go to Via Napoli for lunch and Yachtsman for dinner will feel very relaxed because you have a very short commute to get to both of those! Short walk to YC and short walk or boat ride to Epcot!

And both are very good restaurants!
