Is there any benefit to redeeming 200K twice rather than 425K once? The hotel certificate is certianly more lucrative with 425 (20 nights with the 425K vs. 7 nights for each 200K), but the hotel end seems to be the part I may have trouble using. I have no immediate plans for ten consecutive nights at one specific Marriott--is there any way to break this up for to extend the one year life of the certificate? If I wait to redeem my points, it seems from other postings that this award may change for the worse.
