My holiday in Madrid

I' ve been to Madrid with my friends.
I went one day because my parents were in Guadalajara.
When we arrived in Madrid 's theme park we divided ourselves in some groups.
I was with some friends.
We were walking round the Park when we arrived at the "Abismo".
Abismo is very famous a roller coaster.
It was the last ride we could have that day.
I thought it was quite dangerous, so I didn't want to ride on the attraction, but my friends wanted me to do it.
Eventually, I rode on the Abismo, and I remember that when I came down, I felt ill and very sick.
That day I had a horrible experience, but I admit that it was my best day in Madrid.
