I forgot to mention this earlier.... When I got to the hotel in Brazil, in Sao Paolo after missing my connection to Bogotá, I got to the room and it appeared that there was no electricity... none of the lights would turn on.... nothing. I went down to the front desk and communicated, in broken Portuguese/Spanish, my problem.... It turns out that you have to insert your card/room key into this little apparatus in order to activate the electricity which make it impossible to leave the lights on or the television or anything when you leave the room because you obviously take your card with you... to me, this seemed like a really good way to conserve energy.
