Didn't see the prog but we enjoyed our day at the KSC - this was before 9/11 so I do not know if you are offered the same experience, but I am sure I enjoyed it more, knowing what the highlights were and how to plan the day which I'd picked up courtesy of the UK DIS, Simon's book and a very inspiring enjoyable trip report by Mike (which I even printed off and still have somewhere!!) e.g. we went to see one of the IMAX movies, The Dream Is Alive' asap on arrival.
There were some parts we enjoyed more than others but the most memorable for me was the Apollo/Saturn V Center - from the launch center re-enactment to the moon landing presentation, with the fabulous Saturn V rocket in between and our chance meeting with someone who worked on the shuttle missions.
When we were there, the food was not up to much, but we found the coach loading and unloading was very organised and we went on a busy warm day.
Frankly although I didn't see this programme, once again it sounds as if a lot was crammed into a short space of time.
I think the Discovery Cove experience cannot be so good with a camera trained on you - not quite the right circumstances to get that exclusive, away from it all relaxed feeling, and indulge in that special feeling you get with the Dolphin Encounter.
