Having already done a similar thing on the Amazon, I was a little wary of this cruise. How wrong could I have been - from the time we were picked up and taken to Lake Argyle to the time we were dropped off back home again, it was nothing but sensational - from the knowledge imparted to us from Greg on the way and then continued on by Gary on the boat - to the absolute beauty that is Lake Argyle - to the swims in the lake (not to mention the nibbles and drinks we were able to enjoy as we swam !!) - it was just a delight and I couldn't have been happier that we decided to do this cruise. Thanks Greg to you and all of your crew - excellent
