Hi, we are coming over for a 15 night road trip in August 2017, principally to visit Cedar Point and Six Flags Great Adventure. Flying into NY, we intend to spend 2 days visiting NYC, thereafter the plan is to drive to Niagara, take in Canada's Wonderland, then go onto Cedar Point, return to SF Great Adventure and head home. Any thoughts as to whether we should consider replacing the Wonderland/Niagara leg by taking in Dorney Park and Hersheypark instead?....or is Wonderland the better option? Thanks in advance for any feedback....
