Been rafting twice with this outfit - once with a girlfriend, and once solo. My girlfriend had never done whitewater before, but she had no problem at all and had a blast. They pick you up from your hotel and drive to the site. You're provided breakfast to give you energy for the adventure. The river run goes through mostly class III/IV rapids surrounded by jungles, and the scenery was just fantastic. The guides are professional and very friendly. And yes, they do speak English. Highly recommended, even for first timers.
