By FF are you referring to Flying Fish at BW? If so you have a chance of getting there by 9:30 but might be 5 to 15 minutes or so late. Fantasmic is stated to last 30 but actual time is about 40 minutes and possibly a few longer. Then you have to get out of the stadium and MGM which can take 5 to 15 minutes depending on where you are sitting. Then you have to walk to BW which takes about 15 to 20 minutes -- you could try a boat but if there is a long line for it (highly likely at that time) you may have to wait for a second one and that means you may not get to FF before 10. If you can catch the first boat after Fantasmic take it to S/D (first stop), and get off and walk over bridge from there to BW -- trip from MGM to S/D by boat takes about 8 minutes, walk over from there to BW and then down to FF takes 4 minutes. If you stay on boat, it goes to YC/BC and then BW after stopping at S/D and that takes 15 to 20 minutes from S/D.
