Congrats!
I second just about everything that has already been said here, including recomending The Lodge over Manele Bay. The gold IS great. Something not mentioned yet is sporting clays, if you're into shooting. I believe there is also an archery range now. Doing the 4WD trails would be a good idea, but if you're NOT going to do that, a car will be a waste. There is a free shuttle to just about every place that you could get to without 4WD.

Good luck!
