We are planning a month long visit to Europe in April since my sister in law is getting married in London at the beginning of the month. We have been to Europe several times and are using this trip to visit some of the places we haven't seen before. One on our list is Switzerland and we were planning on around 10 days there, split between Lucerne, Bern, and Geneva as homebases. But, as I was reading Rick's book, it seems as if most of our options will be out of pocket in April or, in the case of the Olympic museum, closed for the year all together. Is it worth even planning to visit there in April or should we look to spend all or some of those days elsewhere? Thank you in advance.
