Package holidays, covering a two weeks’ stay in an attractive location are increasingly popular, because they offer an inclusive price with few extras. Once you get to the airport, it is up to the tour operator to see that you get safely to your destination. Excursions, local entertainment, swimming, sunbathing, skiing – you name it – it’s all laid on for you. There is, in fact, no reason for you to bother anything yourselves. You make friends and have a good time, but there is very little chance that you will really get to know the local people. This is even less likely on a coach tour, when you spend almost your entire time travelling. Of course, there are carefully scheduled stops for you to visit historic buildings and monuments, but you will probably be allowed only a brief stay over night in some famous city, with a polite reminder to be up and breakfasted early in time for the coach next morning. You may visit the beautiful, the historic, the ancient, but timeis always at your elbow. There is also the added disadvantage of being obliged to spend your holiday with a group of people you have never met before, may not like and have no reasonable excuse for getting away from. As against this, it can be argued that for many people, particularly the lonely or elderly, the feeling of belonging to a group, although for a short period on holiday, is an added bonus. They can sit safely back in their seat and watch the world go by. 56.When you go on a package holiday, you don’t have to_________ .
