The older you get, the more 'Life happens' and it's harder to get away for over a week at a time, much less 2 weeks (e.g.: job, costs of family, some people have a problem leaving non-diving spouses and young children behind). So trips to distant exotic destinations become more impractical. My hoped for 'bucket list journey to the moon' distination, a maybe once in a life time 'if & when I retire' dream, would be a contest between Komodo and Raja Ampat. By the time you factor in round trip to/from the U.S., maybe a day to recover, and a 10 day live-aboard to maximize the return on investment and justify the travel ordeal, you're looking at 2 weeks easy I suspect.
What kind of budget are you looking at? How much time can you dedicate to this endeavor?
