Translation of quinina

I was tired and still felt a little ill, so that I agreed to meet the other family and they escorted me to the next building. The new family instructed me not to tell anyone where I stayed here.
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.
We booked a tour for the next two days, one on a boat and the other on foot. In one of the agencies we met a nice couple and decided to stay in touch with them and have dinner together.
