Marriott Concierge-

I have a few questions about the new program.

If I currently have a reservation (7 nights) for March 2009 and a certificate attached to the reservation from a travel package, what happens if I need to change the hotel or dates after Jan. 15?

Will I be able to use the certificate at another category 5 property or will it require an increase in points for a 7 night stay?

Also, what about Marriott Vacation Club properties? Will they still be available for points and is there an increase in the amount needed for a stay at MVCI?

Last question, is there any change in the amount (.0125 per point) Marriott charges to purchase reward points?

Thanks!
