We stayed at the BC in 2010 and BC/YC is our absolute favourite.If you want to be close to EPCOT then try for rooms 1501-1530 as these are on the wing nearest to International Gateway.There is even a secret door and pathway which takes you within 3 minutes walking time to EPCOT
Only about 50% of BC rooms have full balconies so if this is important to you make this your room request, its not a guarantee but worth a try.
In the evening they show movies on the beach which is really cool. Also if you can fit it in head over to Beaches and Cream and try the Kitchen Sink, its HUGE
Take a look at the BC/YC thread on the resort forum, it has pages of helpful information
If you do a search on these boards for beach club, you should be able to find the big mega thread that is in the resorts part of these boards. Loads of pics and a ton of pics.
