Don't take the bus to Epcot, you'll have to walk thru the whole park to get back to IG and then walk/boat to BC. You'll be exhausted before you even have breakfast.
Take the bus to DHS and then walk or boat to BC
or take the bus to DTD and catch a BC bus. I always plan for at least 1 hour transportation time to get from resort to resort.
Have a great time! Cape May breakfast buffet is one of my favorites
