I've long thought that Allandale station would be a great spot for a gateway to cottage country. While more bus connections is always a positive I don't think it would work for most cottage goers/campers due to the inherent nature that they are spread out across Muskoka/Kawarthas and beyond. My dream is that a car rental company sets up at the station with opening hours that coincide with train times. (This would also be useful at Oshawa GO as well).I wonder if GO is looking to position itself for more Cottage Country/north of Barrie bus connections. With some improvements to the Barrie Line already having taken place, and quite a few more underway or on the horizon, Allandale Station could very well become the transit gateway to Central Ontario.
Train up to Barrie, and then take a bus from there. Not very useful for taking the whole family to the cottage, but if someone is already up there and someone else wants to join (ex: a parent had some meetings so had to stay behind while the rest of the family went up), that could be a popular option.
I could see bus connections to Blue Mountain/Collingwood, Wasaga Beach, and Orillia being quite popular.
