Translation of behindert

So I do not know what to write more. It seems that you know my entire life by now. Each sentence needs to be constructed in a differnt way. The best part is to write about vacation and nice memories.
I have been there once for vacation, but I was too little. It was twelve years ago, when I was still a child. I went there with mom and dad and all I cared about is beach and sand, no culture.
I went to the desk of Aerolineas Mexicanas and postponed my flight by two days. I did not have to get prepared as I had done some homework before coming here. The backup plan was Isla Mujeres.
