We have no idea when you are traveling, and
DVC is a product with crazy fluctuations in the chart. If you're trying to go at Christmas for 28 points a night, 50 points isn't going to get you far.
You need to look up the charts for when you travel and work backwards from there.
50 points won't get you far in a 1BR anywhere at any time. 29/32 points at BW, a cheaper chart, in a cheaper season.
I book mostly 1BRs, a 50 point contract wouldn't be very useful to me. And I wouldn't spend closing on it, because that costs makes the points cost so much more. I'd just buy a 100.
