I stayed at the Stage West years ago and caught a dinner show there. I really enjoyed my stay there.
To add to the Wonderland/Cedar Point debate, I used to visit both parks often growing up, and Cedar Point is far superior. If I had the choice, I'd do Cedar Point anytime! The last time I went to Cedar Point, I stayed at one of their hotels, Breaker's Express. It's a short drive to the park, and I remember getting a great rate on the hotel and coupons for the park.
Call 1-800-Buckeye (Ohio's tourist bureau #) and request the Cedar Point brochures. They contain coupons for discounts on admission. I'd also request brochures for hotels in that area.
