We went to Downtown Disney (rebranding as Disney Springs) yesterday to wander around and see the Minions movie (you should definitely see it).
The Boathouse restaurant just opened, and one of the features is the Amphicars https://disneyworld.disney.go.com/dining/downtown-disney/boathouse-restaurant/ or http://www.orlandosentinel.com/travel/attractions/the-daily-disney/os-story-amphicars-delight-guests-at-disney-springs-20150421-story.html)
They are cars that are also boats - they take you for a tour of the lagoon ($125 for 30 minutes).
Pretty neat, but I don't know that I want to spend that kind of money. :)
