Well, of course. If he makes weeks Jun 1 - Jun 22 (let's assume June 1 is the first day 13 months out), of course he wants Jun 22 as the first day of his points stay, which is > 12 months, right? Which he can do after he gets the weeks booked at the 13 month mark from Jun 22. I thought the question was exactly can he do that, and I say yes. You disagree he can't do a points stay Jun 22 and on so he has one continuous stay?
I thought he said he merely wanted one stay and wanted to combine his weeks + points, no? He said he owned 3 weeks. Does my example not work, assuming calendars at the specific resort work?
Did I not say "then called them to book the following weeks at 13 months with points", bold added? I did not say on the same day. I said at 13 months.
But maybe I missed this: "Can I also have a DC point reservation booked concurrently at the third week of my weeks reservation?". I had read it as can he have one continuous stay from previous lines of the OP. i.e., I stopped where he asked "Can I make a 7 week reservation at 13 months?". And the answer is yes, at the 13 month mark for weeks stay, and, 13 month mark for the points stay. Those are just different dates of course. So, not concurrent. My bad for misreading. Thank you for correcting this!
