ahh my local park. Some rides that get overshadowed by the coasters are things like Escape from Pompeii which is an excellent Themed shoot the chutes ride. Le Scoot De flume is a classic arrow flume older than the park itself, and Curse of darkastle is a pretty good dark ride, however, don't go in expecting Spider man, you will be dissapointed....
As far as restaurants go, it really depends on what your in the mood for. Trappers smokehouse is an excellent BBQ restaurant that is my favorite in the park. Das Festhaus is a classic restaurant that serves good German food as well as your regular stuff like Pizza and Chicken fingers. However, if Entwined is playing in there, I would steer clear
(Its a Horrible show). The Italian restaurant is good as well if your in the mood for that.
Try ALL the coasters! Theres not a bad one! My favorites rank as
1: Apollo's Chariot
2: Nessie
3: Alpengeist
4: Verbolten(Much tamer than the rest, but unique and fun)
5: Griffon
Have fun! I'll be there tomorrow and next weekend for the Food and Wine Festival( Which unfortunately you will miss by a week or two).
