(I think placing the bones back might have countered the planned attack. But like Roberts said we have some time before they were planning to attack. I think we should go explore the areas around town to pull in some gold so we can silver weapons for everyone, then come back in the afternoon while its still daytime tomorrow and take care of them. We can camp out overnight out of town once tired. Maximize time exploring.
Go fetch the hunters then head out? We should still have plenty of time to get em. I would make sure the priest super secures that location so the bones don't get taken. And also shut the church overnight and let's nobody inside(vampires have to be invited in.) just as a precaution in the interim tbh.
Either we take care of the vamps now, or do it tomorrow. I say tomorrow tbh, we can start getting our weapons silvered when we come back, stake and take care of vamps in the interim. Then festival and then take our time exploring more if need be while we wait for them to be finished? Or just chill in town with a weeks worth of downtime if Drafter allows us?)
