[LOTR] I'm a mortal who lucked out and was given a trip to the Undying Lands. What awaits me there?

Assume I'm, idk, a hobbit who has born the One Ring. Or maybe I'm just a dwarf who was best buds with a Silvan prince during my lifetime in Middle Earth, and manages to hitch a ride to Valinor. What awaits me there? Do I enjoy any kind of immortality, or am I destined to just live out the rest of my mortal days in a really, really nice retirement village with lots of pointy-eared nature fanatics?

Your status as a mortal is not changed upon going to the Undying lands. If you are mortal, you will still pass away eventually.

It is the only place in the world (mostly) free from the corruption of Morgoth. So the scenery is going to be as pleasant as any you might find in Middle Earth, and probably very primitive compared to the industrial advancements of Men.

If you have any interest in any subject matter, you'll be able to indulge that into your hearts content (assuming it isn't something vile) as for just about any area of endeavor there is a Vala or Maiar who is basically the embodiment of that. Enjoy gardening? They've got an ~~app~~ Vala for that.

It certainly helps to be fascinated or at least tolerable of elves and their way of life, as that is going to be the dominant culture there. But elves are not a monolith and you can probably find a subset that is suitable to your liking. Enjoy poetry and generally admiring the Vala? Hang out with the Vanyar. Enjoy crafts? The Noldor are your people. Like the sea? Check out the Teleri.
