Translation of reactivo

I grabbed a burger from an American fast food chain and swallowed it immediately, as I had not eaten for a while. I boarded the machine and could feel a slight stomachache but decided to ignore.
I took my backpack and looked for a minibus that would take me a little outside of the town to a small settlement called El Panchan. I arrived there very early and no rooms were available yet.
It was a good way of starting the trip. A ferry ride across the beautiful water, a beer in one hand and the unknown adventure lying ahead. I had to look for a place to sleep and checked a few hostels.
