It\u0027s summer season again. European countries have begun to take a long vacation, which called "high-temperature vacation." They started their summer carnival to go on holiday. Most of them are concentrated in July and August. One of Poland clients said, 20 days free of work that you can take at any time. Many people like to go out and enjoy a family trip.
