The local authorities are talking "tourism saturation" at the moment. These are the new bywords which are used by both local government and council officials. Tourism saturation means too many tourists who are causing headaches for local residents and the island's stretched resources. I would say that it is a problem which really only extends to Palma and during the peak summer months. Yes, when Palma is visited by four giant cruise ships on the same day it does cause problems and yes the city does feel overcrowded. This problem could be easily overcome if there was careful planning to ensure that cruise ships didn't all visit the city on the same day.
