Not to mention you'd go from years and years of near 0G gravity to twice the gravity of earth. You wouldn't even be able to walk.

Compare to the difficulty of getting there in the first place, getting spin gravity to work right isn’t a big problem.

I would assume if we can figure out accelerating to near the speed of light, we'd also be able to make a viable rotating spacecraft to use centripetal force to solve that problem.

If you're making this trip in any reasonable amount of time, you're probably accelerating during the journey at least half a G anyway.
