I'm experiencing some ticket confusion, especially with Neuschwanstein tours. We plan to purchase a museum card at the first castle we see (and that choice is weather dependent). Once we have it, do we need to make a reservation, especially for Newusch? The card doesn't work for Hohen because it isn't in the same "family of castles." But the Hohen site is the one that takes advance reservations. Isn't it a little dicey to make an advance reservation without knowing what the weather will be? I hope someone can help. Thanks.
