We are considering a trip in December 2013 - our kids will be 8 and 11. They love animals and are great swimmers and hikers. I read about National Geographic expeditions that sound amazing ($$) but some travellers have been bothered by kids (I would hate for mine to be a cause for concern - although they list a family trip). We have been recommended the adventure center (a UK based group who offer family adventures specifically) and goway (they seem to have less detail on their site) and backroads (trip too short in my opinion). I don't know what the boat names are except for National Geographic (Endeavour or Islander - more posts I saw about Endeavour). Any comments or guidance? I like the idea of 8 days on a cruise.
