The number of points for a week depends on a couple of factors; the size unit you need and the time of year you want to go. As you might suspect, a studio takes fewer points than a 1 BR; and a 2 BR takes even more. Similarly, the points needed during the slow season are fewer than you would need if you were going during a busy period.
Yeah, I know - not a real answer to your question. Sorry, I just don't happen to have the points chart handy right now.
