Yes. Thus far the promotions have had a 'price' for enrolling 2 resale weeks and then a higher price for 3-7 weeks. Grand Chateau Platinum 2BR is 3275 and 3BR is 4625, Grande Vista Platinum 2BR is 2775 and 3BR is 3725. These numbers and a great deal of other useful MVC information can be found on
https://vacationpointexchange.com/ (which also is a platform for renting Abound Points).
And Abound Points can be used for a year, but they can also be borrowed and banked. The length of time they can be banked into depends on the number of points and enrolled week point equivalents you own - an additional 12 months for lesser tiers, 18 months if you own 10,000 points, and 24 months if you own 15,000 points.
