At present there are more and more ways of going on holiday. In my opinion, there are two types of holidaymakers.
   Holidaymakers of the first type always go to seaside towns or mountain resorts when they go on holiday. Their only aim is to relax. They just enjoy the local scenery and play the sports they like.
   Holidaymakers of the other type go to foreign countries to increase their knowledge. For them, going on holiday is educational. If they come to a place, they will stay until they get a proper feeling of it or fully enjoy the local food, wine and their special culture.
