We want to go to a Maldives atoll with the healthiest coral, sea anenomes, sea fans etc. for 6 full days at an upscale resort (~$600-$700/day with tax) with breakfast and excellent dinner). We also want to go to a remote Indonesian remote resort with A/C for 6-7 days that would have different formations under water, if you have any ideas, as well.
We also will go to Kuala Lumpur to visit friends for 3-4 days while on our trip at the time to minimizre the cost ost of the coach air fare.
