Translation of messy in Spanish

After this strange stop we moved on to the city center where he left me. I was on my own now and started to explore the little streets of the old center. It was packed with international visitors.
The other visitors in my group were from the United States, Canada, Germany and from other parts in Mexico. I need to say that it was so much fun to meet people and spend an entire trip with them.
I connected to a group of people and we played some volleyball, had some drinks and they told me a little about the place and the country in general. I returned to the hostel and took a cold shower.
