Was getting excited about Lucerne seeming like great 5 day May holiday for me, DH and two boys (4 and 7). Was thinking transport museum, mt pilatus etc. But the more i research, the more i hear it is crazily expensive. Have people been and confirm just how expensive it really was ie a bit or eye watering. (I'm used to London prices if that helps for context!). If not Lucerne, anywhere else you'd suggest? Fun activities, not just a beach etc
