Thanks, OP!
As I begin evaluating miles vs. points, I caught the fine print:
Members who choose ®Aeroplan in their Membership Profile will earn a minimum of 250 Aeroplan Miles per stay or 2 Aeroplan Miles per $1 (USD) spent on room revenue, whichever is greater.
Note that if you are staying for just a night, you are guaranteed 250 miles. Might be a lot better than points. If you are going to stay for more than a night, you could always change your profile back to points.
