I want to say yes, but I don't know for sure. I'd have to have a comparable project in a similar climate. The best that i've found for a comparison is the Hong Kong Gondola system.So basically long for a gondola but quick for Disney.
Hong Kong (Ngong Ping 360) took a little more than 2.5 years, but used public funding and also ran into some snags due to a Typhoon that hit. Started beginning 2004, opened September 2006.
