The duck rides (boat rides) can be awesome. That was one of our favorite things there. If you have the spare cash, a ride on the SCAD dive or bungee jump at Extreme world is amazing (though overpriced)
We did the Original Ducks and it was really fun! You have to ride that. THe Top Secret thing really left me with a sour taste as it was $12 for 10 minutes of dumbness. Hit some of the haunted houses too. One of them scared the heck out of my girlfreind :). The gocarts at BC rock too! Don't forget Avalanche is supposed to be open Sunday at Big Timbers from what I have been reading.
When you do the coasters at Mt Olympus, there is a slight chance they might not check your seat belt. Please be prepared for that possiblity so you don't almost die again. Also, they may not card you for the last seat of Cyclops. (You must be 18 to ride that car.) The ejector air at IB is NOTHING compared to that seat, and there is only a buzz bar and a seatbelt that can easily slide loose. Just a heads up for you.
Kyle, Kalahari is a bit farther than two miles from Big Chief. Kalahari is located in the town of Lake Delton, while Big Chief is located in the town of Wisconsin Dells. There is a good stretch of road, especially by the Wilderness, and the Wonder Spot that has no sidewalks and is extremely dangerous to walk on. Timber Falls is even further, closer to downtown Wisconsin Dells. I would recommend driving to and from each location. Many of the roads around there are VERY busy and are less than pedestrian friendly.
Have a good time, and tell us all how Avalanche is! I'd go on Sunday for the opening but I have too many plans already. :(
Wow, I guess THe Kal is further than I remember. My trip there this past June was so packed because of work and it was a whirlwind. Next time I go I will have to pay more attention to what is all over. Cyclops in the last car was an experience though!
