I am pleased to see this new venture starting up in Goa. I have used hop on/off buses in many countries and I almost always find them worthwhile. I would definitely use this one. For some reason, when I go to Goa I fall into some sort of stupor where I only get as far as beach shacks during the day. This may help me to see a little more! I am not like that in any other country I go to!
