Maine Narrow Gauge

Hi all. I'm thinking of a trip to Maine possibly in summer 2021. I've found the Maine Narrow Gauge RR & Museum, Boothbay Village, Seashore Trolley Museum, and Wiscasset, Waterville, & Farmington Museum. I know I definitely want to see the WW&F museum, so there's a Saturday right there. Is it possible to do two or more in one day? I know the Maine Narrow Gauge Museum is open daily, but not sure about the others in summer. What would be your suggestions as to how to do it to get them all in if that's possible? I'm trying to determine how many days it will take to actually see everything here. Also, want to see Acadia National Park and see the lighthouses around Portland. I'd love to hear from the experts!!

Thanks,
Jim
