Congratulations!!! You have picked the ultimate resort! Here's a list of great things to do/see on your stay at BC.
When you arrive, say hi to Art. He is awesome and has the best personality to set the happy tone at the resort.
The rooms are light colored and airy. They remind you of being at the beach. I love the lamp on the desk in the rooms.
Eat breakfast at Cape May Cafe character breakfast. We ate there two days in a row because DD16 loved it!!! Great food and not so crowded that the characters are in a rush. They have plenty of time to play with you, especially Goofy! Try the gelato from the Marketplace, where you can refill your mugs. Not sure what it really is, but it is awesome!!!! Beaches and Cream and Hurricane Hannahs are right at the pool and have great eats. The Yacht Club Galley (now has a different name, but still the same great place) is great for dinner.
Go to the BW in the evenings to hang out watching the street activities and even watch the Epcot fireworks.
SAB is great! The water will be heated if needed. It is a large pool and has a great slide. There are places you can sit and see most of the area where your children will be.
Location at BC depends on what you want to be close to. I requested close to Epcot so that DS17, DD16, and DD's BFF could have easy access if they wanted to go without me. It ended up that DS and I went over there most days and picked us up some lunch from the different countries while the girls went to Hurricane Hannahs for their lunch (they have no food adventure!!) I would dedide what you want to be close to and just request the area. It worked great for us. It took us only about 2 minutes to be insde Epcot from our room!!!
Here's the bad part.... if you need something from your car, have your walking shoes on. There, that's the only bad part I know of. I would say that the good outweighs the bad a lot!!!
Enjoy your trip!!!!
