You can call up and see if you can get this free night promo posted by FlyBalletGuy: https://www.aeroplan.com/en/offers/p...jun072005b.jsp

Also, request a status match or challenge based on your SPG status.

The Marriott Visa, as psychephylax mentions, is a good idea. If you don't know someone who has a card already, feel free to PM me or another member of your choice for a referral bonus. All you have to do is give them another member's MR number.

Finally, if you have some reservations booked, the CS rep might also be willing to sign you up for the summer promotion.
