As for me, my favourite travelling destination is Egypt. I've been there several times and hope I'll visit it again soon. I love the kind of travelling Egypt offers. It is always warm and often hot there. I really enjoy this kind of weather. The sea is also warm. I enjoy laying on the beach doing nothing. Once in a while I participate in animation activities. I love playing volleyball and doing aquagymnastics. But Egypt isn't always beach vacation. I liked to trip to Cairo and Luxor. These are the places all humans should see with their own eyes.
