I had assumed they were one and the same. A look at the floorplan on the website seems to indicate that there is not a full kitchen and likely just a mini refrigerator: http://assets.sheratonvancouver.com/...amilySuite.jpg

ETA: There was an issue with the website when I was booking, so I booked over the phone. I was just booking a regular suite and the person on the phone told me she could guarantee the 2 BR since I'm platinum. I booked it a couple of months in advance, I think. Anyway, we did indeed get the 2br, so if you really need a kitchen, maybe give them a call. Maybe they'll do the same for you.
