Nezy,
We just returned from a short trip, our first time home at BCV. I really liked our view, it was of Epcot Spaceship Earth and The Land and we could also see the fireworks from Illuminations. It did have a terrace - sort of small but enough room for two chairs and a small table. It was room 559. There is a road down below but we were not bothered by the noise being on the 5th floor.
Good Luck with your plans!
