I think the best value would be the COMPLETE TRAVEL PACKAGE - Code 082. It would give you 100'000 miles plus a cert for a free week in the hotels of category 1-5 - price: 215'000

Here is the link: http://www.marriottrewards.com/awards/packages.asp

By redeeming for FF miles alone you would get 100'000 but for 250'000 points.

I don't know If you MUST use the miles as soon as you redeem an award with Marriott or if they transfer the points directly to your airline account and you can just keep them or add some more for a business or first class award. Maybe somebody else here knows the answer.

Hope that helps.
