Translation of hoffnungsvoll

Although I put my wallet in the front pocket of my pants it was not there. I had been so diverted by the aggressiveness of these kids that I did not feel it when they grabbed it out of my pocket.
I even put on my Poncho, a plastic rain coat, in order to protect myself from the aircon-breeze. Somehow I managed to fall asleep and woke up at around six in the morning when we approach Palenque.
Luckily the town was small and the hotel manager could call all taxi stations. They checked it through their radios and an hour later the driver was back with our bags. He did not want to be paid extra, but I insisted.
