Yes, but only if each night at a separate hotel. Ie, the promo is 8000 points for each two stays, and a stay is defined (in every hotel program) as any number (1+) of consecutive nights in the same hotel, no matter how many times you check in or check out.

Btw, if past predicts the future, they're likely to have a promo this summer sometime (after a bit of a gap between promos) which they'll say is "stay 2 times and get a gift card", but in actuality if you stay 2 times you'll still get 8000 points, it's just that during the summer they'll have a promo where you can (but don't have to) redeem 8000 points for a gift card.

So if you "look under the hood" of each promo, they tend to have stay 2 times earn 8000 points promos of one sort of another in spring, fall, and summer.

However, even though the winter promo is typically different (for example, double points), this past winter they didn't have a stay-based promo at all, and we still don't know why, so we don't know if any of their other patterns from the past will also break this year or not.
