If you’re not planning to come back before September you’re really just at the mercy of whatever is left on the website. It’s more likely a random 1BR will be open on a day or so here and there in the middle of your trip. I imagine availability is getting kind of sketchy in April. If you can and it’s still available, I’d recommend booking your reservation into multiple separate reservations. That way once you get the points you can modify one of them and drop off a date, and then use the 50 points from the other contract to book whatever random room is available. It’s a lot of work to do this though and you’ll likely have a random day at some other resort and have to switch rooms back afterwards but if you REALLY wanted to save thise 50 points this is how I’d do it. Debatable if its worth it.
