i've never been on a cruise, but i've been to hawaii several times.
you're correct about the flexibility you have on the island. rent a car and you can go anywhere you want. there's plenty to do in hawaii (but stay away from the touristy places) and you can isolate yourself, but only to an extent. (somebody recently did a hawaii thread...there was a lot of good info in it).
but, i suspect a cruise is also pretty kickback. in reality, do you think they really give a hoot if you don't engage in all the activities? the only thing i always wonder about a cruise is just how crowded it is on the ship? it seems like there would always be people around you? plus, aren't the cabins kinda small?
but, i think either choice will be solid for ya. it
seems like you're leaning towards hawaii....so go there first!
