A. My five elements to enjoy and value in life are love, food, fashion, entertainment and travel. But one element that includes the others is travel. With the mention of travel, my eyes glisten and heart begins to pound. My favourite saying goes: 'A hopeful heart and an open mind are the best travelling companions'. During my trips I do my best to follow it. Travelling for me is experiencing and learning.

B.You can't get lost in an unknown place with Travelling Companion Panorama Camera. It is an optimal tourist technology. This cutting-edge concept is a device that combines the capabilities of several different gadgets and aids that out-of-towners often find useful. You can hold this device in one or both hands and have a clear display in front your eyes. It can help you to map your routs, to discover places of interest and to record your trip.

C. Those who love to travel, take every opportunity to ride on anything but enjoy the ways and the items at every stop. The most pleasurable feeling for them is when they have someone with whom they can share their happiness, with whom they can talk and relax. Nobody wants to be alone in the world and while enjoying something which one is very fond of like "travelling", one feels the need of the right kind of companionship.

D. As John left the wood, a voice called after him, "Hallo, comrade, where are you travelling?" "Into the wide world," he replied; "I am going into the wide world also," replied the stranger; "shall we keep each other company?" "With all my heart," he said, and so they went on together. Soon they began to like each other very much, for they were both good; but John found out that his fellow traveller was much cleverer than himself. He had travelled all over the world, and could describe almost everything.

E. We have a list of people willing to use vacation time from their job to accompany you on vacation. While none of our clients may need a doctor or a nurse to get around, all of our travellers enjoy the comfortable feeling of travelling with a companion who has professional education and experience. You can talk directly with each companion about your needs while travelling. An experienced travel companion can solve most problems in advance and handle other challenges as they arise.

F. Like all little girls, I had an obsession with Barbie dolls. Once I was presented with a doll named Samantha, who had a bright red velvet dress and matching bow in her brown hair. She came with a little travel coat which, in the words of my mom, made her the perfect travel companion. The doll was fantastically lovely and cute and I couldn't part with it. Even growing older while travelling it was always in my baggage waiting for my company.

G. A Travelling Companion is "a person or persons with whom you have coordinated travel arrangements, who shares the same accommodations as you and intends to travel with you during the trip". These are people you are not related to — those people are usually family members. Usually "Travelling Companion" means up to six persons whose names appear with yours on the same trip arrangement and who, during the trip, will accompany you.
