So if you take 8 hours to rest and heal up, that will put you at around 7 PM, with maybe about two hours of light left, and you're an hour from the den. It will let you heal for Con modifier x level, which won't be enough to fully heal you, and won't remove your Wounded status. For that, you need Treat Wounds or to be fully healed. But Silvi would have her healing spells back.
You have time to Treat Wounds before you rest. If you rest fully to the next morning, you can recover Con mod x twice your level. Still some of you won't be fully healed or clear wounded though. You can camp another day, though.
Do folks have rations, or do you and Noala need to do some hunting and such?
