From What i got from Both The NBC and CBS broadcast of the Parade and Smurf balloon, these are the dimensions, that i also got cofirmed from another source.
The balloon is 58 Feet Long, 38 feet Wide, 47 Feet Tall, and with the smurfs at three Apples high, It could hold 30,000 Smurfs,
Thats a lot of Smurfs.
