Enjoy the independent travelling while you are (I think) young, or young-ish.
Like I did for about 40 years; Russia, west Africa, South America, all over Australia and Nth America, you name it. Unfortunately, with age, for most of us, comes compromises, including the ability to travel as we once did.
That was part of my reason to begin cruising a year ago; plus where that cruise went to (Kimberley coast), its very difficult to travel independently and see the relevant sights. Even in my work, 4WD-ing all over Australia, I never saw anything like it - including Kakadu. Access via zodiacs off a small cruise boat is ideal. My next cruise, to Falklands, Antarctica etc is also badly served by all-inclusive resorts
.
As I said, enjoy the independent travel while you can and I hope you maintain it as long as possible. Eventually the need to compromise will loom.
PS one pro of a cruise that an all-inclusive resort can't match is that it moves
. Visit more than the local bar or beach or restaurants day in day out. Visit multiple countries, cities and experiences instead!
