LANSING, Mich. (AP) - The state Department of Natural Resources is planning to launch a new reservation system for state park camping, lodging and harbors. The central reservation system opens Nov. 1 for state park lodging, including camper cabins, mini-cabins, rustic cabins, yurts and modern lodges. Those typically have a year reservation window. On Nov. 3, the system opens to facilities with a 6-month reservation window, including campsites at state parks and select state forest campgrounds and slips at state harbors. For stays with an arrival of Nov. 1 or 2, campsites will be available at parks on a first-come, first-served basis. The DNR Parks and Recreation Division has contracted with Camis USA Inc., to provide the reservation system, including a call center in Ann Arbor and servers in Southfield.
