Plenty of good advice here, but none quite as valuable as the above nugget from FF.
Please make sure you have a decent level of post qualification experience before embarking on this trip (sorry, but the language of your post suggests you might not). Just because you are entitled to do something under the terms of your rating, does not mean you should launch straight into it.
I had four hours flying off the AI with an FI in the week before my first water crossing. I was grateful for every second of it as that horizon disappeared, the sky merged with the water and the view ahead was of bugger all use in maintaning straight and level flight.
