Mt. Olympus amusement park in Wisconsin Dells, Wisconsin, is adding a 360-degree inversion to its largest roller coaster. The ride also will get a new train, which will allow the cars to rotate and pivot properly. Meanwhile, owner Nick Laskaris said the park's advance bookings have increased over last year. "The reasons we're doing well is because of our amenity, and because we're doing a better job marketing, of telling our potential consumer what we have. Internet is our number one tool for marketing. TV is still good, but internet is the best. It's inexpensive, easy to offer specials, and it's live," he said.
