Congratulations VC - You are so going to enjoy the Barrier Reef! I'm green with envy.
Mrs KH and I were married in Thailand (no she's not Thai) and it was magical. She paid me back by winning air tickets to anywhere in the world, se we went as far away as possible and toured Australia. Those sort of trips you never forget.
If you get to Cairns, the early morning Balloon ride over the Tablelands is great. B)
