when you call you need to speak to an agent at airmiles that books package vacations as they go thru Holiday House to book it.
i had inquired about booking a std room at a moderate resort (POR) for 7 nts during value season and the quote was just under 10 000 air miles. plus you have to pay $30. per person to them as a booking fee and pay the taxes (12 or 13% i think, on the total value of the room at rack rate) in cash. no refunds/no cancellations (although you can purchase cancellation insurance thru them if you had to cancel for medical reason and then could get your air miles back...)
