I didn't get to do either. Welcome to my life.
We actually knew before we had even begun travelling north that we wouldn't be able to kayak up the gorge, apparently, a bit like Kim, the park authorities were a bit worried about me (and probably Kim) getting eaten by a crocodile (but for the record no one asked me for my opinion). So we went to Plan B - a breakfast cruise up the gorge instead. This option had its benefits (and they were more than greasy bacon and hash browns to settle the stomach after a few too many drinks the night before).
I should probably mention that I only agreed to this option on the absolute and unconditional condition that we do the full three gorge cruise, not just the two gorge cruise. We did the two gorge cruise.
Despite these little hiccups in my otherwise immaculately planned holiday, it was still a wonderful cruise, and something I would highly recommend. To be honest, I don't think the third gorge would atually offer that much more (at least that's what I'm telling myself).
what? excuse me? ahem? Puede repetir, por favor??? ... if there's no more crocodiles above this point then WHY THE FRICK COULDN'T WE START KAYAKING FROM HERE???
Why do people always seem to forget that it is all about me ...
