(You have a plant where you want a planet.)

How could it possibly take centuries? Aside from a global collapse of civilization, that seems pessimistic to an absurd level. It didn’t take much more than ten years to go from first orbit of anything to first man on the moon. First tourist around the moon will happen in a few years, first tourist on the moon a few more years after that. And if Musk gets his way, Mars next.

I stand by the point (although I didn’t say many many centuries). A lot of development needs to happen before there can be tourism on other planets. Unless tourists are willing to go into suspended animation or space travel and near warp speed becomes possible, we are looking at probably just Mars or Europa as candidate destinations.

Will civilians be able to travel to them in manner similar to what we call vacations within the next hundred years? I doubt it.
