Can I unpause early?
Yes. (Though there may still be a bit of cleanup that I haven't yet done regarding that. Should only be cosmetic, though.)
If so, what's the maximum pause time?
(For vacation pause, I presume)
Should be 3 weeks. We went back and forth on the right length of time for a good long while. Remember, though, that vacation pause also keeps things like your estate and army sponsorship, so it can cause a big problem if you're going to be gone for a significant length of time.
In the end, we felt that 3 weeks should be adequate for the vacation pause, and if you are going to be gone from the game longer than that, you really need to use the cold storage pause, and accept the consequences.
