My husband and I are flying in/out of Frankfurt at the end of November and will be in Europe until December 15. We know that we will be in London for the later part of the trip (e.g. December 10-14). Other than that, our itinerary is totally open. In other words, we have about 12 days of unplanned time.
I feel like we're going to Europe at a strange time (winter but pre-holiday) and I"m wondering what people enjoy doing at that time of year.
