Or Aeroplan web site list of hotel chains. MGM is good but no Aeroplan Miles.

Wild suggestion: Get a SPG Mastercard (5,000 Starpoints), stay at Planet Hollywood/Sheraton (5,000 Starpoints first stay Mastercard bonus if paid by Mastercard), accumulate 10,000 more Starpoint through hotel cost + more spending: Total 20,000 Starpoints. Convert to Aeroplan Miles by Dec. 31st and get 27,500 Aeroplan Miles...

Or get 3 Aeroplan Miles for every US$ spent at Planet H

Good luck in Sin City!
