It looked like it will rain on Fri, Sat and Sun when I visit Lucerne. I would like to get suggestions on plan B.
I was planning to visit old town and take the golden trip to Mt Pilatus. With the rain, I think I will have to do one day at the Swiss Transport Museum. I think I can still visit old town with some rains. I'm not sure if it's worth to pay for Mt Pilatus when it rains.
