I don't know the exact name of the excursion but I really want to do the new Kayak & Nature tour excursion on CC. I have dubbed it the "quad-athalon tour". You walk 40 minutes, then kayak an hour, then swim for 30 minutes, then another 20 minute walk. My family thinks I am nuts, I am not very active and still overweight (although I am loosing quite rapidly right now). My question, has anyone done this and how did you like it? Also, how active or strenuous is it? My step-father kinda wants to do it too and he is near 70. Also, my 15 yr old may go too. I hope I can do it without having to be airlifted back to the ship!
