If you can get to the gate a little early, EE is very much worth it - unless you have no interest in FantasyLand. If you want to do EE, here is what I would recommend:
1. Have your body in line at the DL gate at least 15 minutes before EE starts - 30 minutes would be better.
2. Go directly to FantasyLand
3. You can pick and choose your rides, but the two whose lines will fill up fastest are Peter Pan and Dumbo. After that it is Alice in Wonderland and Matterhorn.
4. Do not use EE time to ride Space Mtn or Buzz Lightyear. You can get FastPasses for these and ride them any time of day with a short line. Not so with the Fantasyland rides.
