Actually, if you think about it, any limitation of rest is completely pointless at the moment.
First, Larian would have to fix the events in the camp at least so that they could queue up rather than overwrite each other.
Despite having almost 200 hours on the meter, until today I have not seen Astarion's scene with the stars (if it weren't for YouTube, I wouldn't know it exists).
This is the real problem. Until this is resolved, any rest restrictions do not make any sense
