Couple of questions please. We are flying from Lima to Cuzco and then going directly to our hotel in the Sacred Valley where we will spend 4-5 nights and visit MP during our visit there. Then, we would like to go from SV to Puno via Cuzco to visit Hayu Marca and the Floating Islands. My question is, how many nights must we spend in Cuzco before heading out to Puno via the train to avoid altitude sickness? And do we need to spend an extra day in Puno to acclimate before spending a day sightseeing there?
My second question is - how many nights are needed in Sacred Valley/MP area to have a relaxed visit and take time to acclimate to the altitude...is 5 nights too many?
Any thoughts are appreciated.
