Translation of escoria

It turned out that they did not have a license to house foreigners but I was too tired and besides, where else would I go. Furthermore they insisted that I should not bring prostitutes to their home.
We left on time and the route included some nice beach towns along the coast, such as Tulum and Playa del Carmen. Behind me sat two very cute girls who started to talk to me about life in my country.
Not worth mentioning. The next day we spent the entire day in the mall buying unuseful things, cheap Jeans of poor quality and again gifts for our friends. I remember buying swimming pants in the sports store.
