Most likely. I only ever really needed today and tomorrow. My only full detriment is that I might not have Internet Friday. It's only a small chance, but still something that will need to be considered.
As well, the schedule is incredibly flexible: if I miss the 21st, then the 22nd is just as logical, seeing that the RP picks up one day after the catastrophe. And if THAT doesn't work, then this will be a Christmas present.
At the absolute, most horrendous worst, then this will be the first RP of 2013.
