We are planning a 4 day trip to Switzerland from London (hubby will be there for work) and can only take off 4 days and 5th day we fly back to states. After reading many posts it seems that wengen is a winner..what airport should we fly in? And should we stay in lucerne or wengen. We have the baby so we would want to do easy hikes. Is this the region we should stick to or somewhere else?
