The only comment I would make re your post is that the dollar's in hand should represent 4 -6 months worth of walking around money. Further, if a "holiday" occurred, I would use as much of that money as I felt comfortable doing before the "holiday ended because it would likely buy much less afterwards.
The bank holiday in Argentina lasted 5 months or thereabouts. With the U.S.A. being so big one would think they would settle matters quicker than that but who knows.

The link above is an interesting article. Whether anything like this is in the works or not, the article is definitely thought provoking.
