“It is ludicrous that visitors who are paying tour operators, airlines and hotels, pay nothing to Britain’s museums and art galleries. When you visit a museum as part of a tour party, you are imposing on others. The arrival of a large crowd in front of a museum treasure is disruptive for other visitors. A group can effectively take over an entire room of a museum while the guide gives a lecture. The least you can do, if you visit a museum in this way, is pay entrance fees.”
