A Sustainable Amusement Park

My good friend Nathan and his family are in Copenhagen this weekend, and this afternoon we went to Tivoli Gardens, Denmark' s main tourist attraction. Aside from the usual ride and activity information, the brochure also had blurbs about how windmills power the rides and a refundable cup system where you have to buy your drinking cup from the restaurant and you can redeem your money buy returning the cup. This is also the cleanest amusement park I've ever seen. If Disneyland is based on Tivoli, then perhaps they should pick up a few more tips.
