We stayed at the BC two years ago and stayed in a Garden View room,so a Water View would actually be two standards above what you have booked.
Standard View is usually looking over rooftops/ car park. Garden View will be looking onto anything green(woods,grass etc), and Water View will be looking over a quiet pool or maybe SAB, then after that is Lagoon View,which will be overlooking the Lagoon towards the Boardwalk. Also only 50% of rooms at the BC have full balconies the rest are called Juliette Balconies (i think) which gives one person enough room to stand on. You could also look at ground floor where you'll have a patio.
If you head over to the Beach & Yacht Club FAQs page on the Resorts Board they have loads of information.
Sorry i cant help with price though.
