We have 2 days from Zermatt and Zurich to visit 2 of the alps mountains. Cannot seem to decide whether to visit Mt. Pilates or Mt. Titlis or Jungfraujoch. We can do any 2 of the three alps. We will be with our 9 year old daughter and traveling in August 2011. We live in sunny California and have seen snow before. We will most likely be taking escorted tours to these mountains.
