Standard rooms do not have balconies. They don't even have Epcot views. That doesn't, however, mean you won't have either or both. The staff is very good about giving you the view you request and a balcony, at no extra charge, if anything is available at the time.
Obviously, the only way to guarantee the deluxe would be to reserve that room at a higher rate.
And, yes the Swan does have rooms (in the east wing) with Epcot views.
