I agree with shellyj about 7d here, but I'll add:
considering the rides open for emm, is pretty big. I also don't think 7dmt is really all that, but the theming and the photo/video that comes with it, make it really fun. As a roller coaster by itself...meh.
Now, with the other rides, if you like those, then add that into the equation.
Also, factor in the pictures you can get. You will not see very many ppl once you get in. You can take some really great photos, if you'd like. Be prepared with the photos, though. That is VERY precious time.
Another thing: the breakfast is not garbage, they put out a very nice spread.
If the rides, pictures, breakfast are things you'd like, the cost is a no-brainer, imo. You also have a major head start on the rest of the crowd for the day. You should be able to slip in a decent 2 to 3 attractions after rope drop, and head to breakfast to relax, gorge, and recharge. Then you have 3 fp to burn, and a leisurely tour for the rest of however long you'd care to stay.
