Perfect vacation. What does it meat to you? For everyone it is different. For some people it is resting in the shade in front of the sea and reading a book. But some people like more adventurous vacations, such as riding a horse through a forest or  surfing the waves of the ocean.
As for me, I like to have fun on my vacation. I like to travel abroad, to meet new people and to discover new cultures. Perfect vacation for me is to have fun in the theme park, getting to know new people, getting new friends. 
Everyone has different understanding of a perfect vacation, it depends on the type of person and their hobbies. But i prefer to have fun. 

My best holiday I spent with my girlfriend, we rested and stayed 4 weeks in hotel Kempinski in Bodrum, Turkey. We flew on an airplane in Turkey from Cyprus. It was the second time in my life because I was there last year with my boss and their children. 
My holiday was exciting and full of joy. We saw a church, museum and drawings street scenes, landscapes, statues, some of the most famous masters’ work. We bought unusual souvenirs. 
We relaxed at the beach and we got a nice tan. During travel across Turkey for four weeks we saw several beautiful cities Kusadasi and Izmir, cultures that exist on this continent. There was a concert of Turkish Pop group, we went there danced, laughed and enjoyed these days. 
Each day I woke up with excitement, ready to go and explore the new place. I enjoyed it immensely. It was wonderful our holiday in Turkey, holiday was full of adventure. Each night I fall asleep and dreamt of what tomorrow would bring us. I am looking forward to going there again soon.
