We just returned from Mackinac Island where we shared one of the Arrowhead Carriages with another couple. The price for the one-hour tour is $100, so split among the four of us was about the same price as their competitor. HOWEVER, Arrowhead Carriages have seating for four adults only, and the driver speaks with you as you tour the island. Their competitor's coaches hold a LOT more people and their narrative is over a speaker system.
I think the photo currently used for this attraction on Trip Advisor is incorrect, and have attached one of the photos I took today.
Would not hesitate to recommend this company.
