Agree about Zion, we've essentially stopped going there except in the dead of winter.
A buddy and I did the Virgin Springs/Saddle Horse as a 2-night backpack in fall 2019 and it was wonderful, it's one that I'd repeat for sure. If you don't mind carrying water and conditions are good, spending a night up at the top of Swazy would be fun. We didn't see evidence of people camping up there, so a real light touch would be good.
If I can't manage to make it further afield, will probably do the Cottonwood Wash/Spring/Nates loop in the swell this spring.
