I haven't seen Fantasmic either so I don't know where good seats would be. I heard that people get their seats super early and I don't want to sit forever waiting. Anyone else have something to add as to whether these are good seats or not?
Package seats are guarateed (up till 30 minutes before; then they can and sometimes are opened up to the general public) seats, NOT preferred seats. They are to the far right of the stage. The best seats, IMHO are in the center, about half way back. Right up front, you have a chance of getting a little wet! However, you can see the show from every angle. I just don't like sitting right up front, especially if it's a windy night (wet!).
With the package the waitress will still tell you to enter at around 45 minutes before the show to ensure you do get a seat. The package seats are also first come, first served. I enter at 45 minutes before with the package and either 1 hour before to 45 minutes before without the package.
I have done the package many times and have now gone to see the show without the package the last 3 times. I have never waited in a line nor have I waited any longer than an hour in my seat. I got great seats each time, in the center, half way back (without the package I mean). I've done the package the end of Aug, Sept, Oct, Nov and Dec and saw the show without the package the end of Aug, the end of Sept and the end of Oct with great results. One time when we did the package, I just walked in the regular entrance to see how crowded it was and ended up sitting in the center and saved my package voucher as a souvenir.
The package is only necessary at very busy times of the year or 'maybe' on an EMH night. If I'm not certain of how busy a time of year is or if there isn't a second showing, then yes, I'd book the package, otherwise, I'd take my chances and eat where I want to and see the show without the package and probably get better seats.
