There are lots of places that are in problems due to the amount of tourists. Try to get into the Eiffel tower for instance...you will have to wait for hours because the third level is so tiny and there is limited space for people. So they are now looking into expanding level 3. Another example is Robben Island in Cape Town. When I went to Cape Town recently asked for a ticket to Robben Island but they were fully booked for the next 10 days. The Inca trail to Machu Picchu is also so popular that it wears down the path. With more and more people traveling we will experience things like this all over the world...it means that you have to plan your travel better in advance.
Thanks Happy shopping
