Are you talking about exoplanets, or the "just admit that every round solid object in space is a planet and there are a lot more than nine in the solar system" planets?
Pluto is here, so minor planets count. That leaves at least Eris, Haumea, Makemake, Gonggong, Quaoar, Sedna, Ceres, Orcus, and Salacia as vacation candidates.
There are 19 more planetary-mass moons to consider as well, if orbital designation isn't important to your stay. (I'd say it's a bonus, as you can see some sick eclipses.)
I mean it could be better, though. Could do with fewer natural disasters, or perhaps another continent in the Pacific so it isn't so empty. Or maybe burritos that grow on trees and a mild concentration of opium in the air. That's the Earth I'd want to live on.
I guess it depends on what you consider an S tier space. I haven't been to Jupiter but I hear they have a cyclone on the pole surrounded by 5 other cyclones. Being in orbit of that would be a (for lack of a better word) religious experience.
It could be broken down into a couple of further categories somewhere in the middle:
Where probes have landed - Venus, Moon, Mars, Titan, a couple of asteroids/comets.
Where probes have only flown past - Mercury, a few asteroids/comets, Jupiter and its' main moons, Saturn and its' moons (except Titan, see above), Uranus, Neptune, Pluto, Ultima Thule (now officially named 486958 Arrokoth).
EDIT: on further thought, there's another one in between those two.
Where probes have orbited - Mercury, Venus, Moon, Mars, Jupiter, Saturn.
