I am thinking about trying to purchase the ovation certs, but don't want to do so only to find that my hoped for days aren't available.

If I book a 7-night stay in the cheapest category now, and then am able to type quickly enough to purchase the certificates, can I have six of them applied to the existing reservation, or must the space be available irrespective of my reservation when I actually have the certs in hand?

Actually -- in thinking about it, this is really two questions. The first is, can you use fewer ovation certs than your reservation is for? For example, can you use 3 for a 6-night stay and pay for 3 nights. Second question is whether, if I book now with a Fairmont room available, I can convert some of the nights over to ovation if I win the certs.
