Doubletree Niagara Falls has always been an eligible resort and I've gotten credit there before. Received credit again three business days after the charge posted -- credit posted as 'NEW MERCHANT'. Spent $199.90 USD there -- since restaurant and Starbucks charges all can be charged to the room its easy to top up (though hard to get exact as the CAD keeps fluctuating). I booked a regular rate (actually double points rate).
