I got the Marriott World Center for $75 plus the $5 bonus through biddingfortravel.com and think it's a good deal on a great property. The dates are dec. 6-10. However, for those dates, Marriott is now running specials like $73 a night for a regular room or $101 for a huge 1 bedroom "villa" with full kitchen, washer/dryer, living room at it's Grande Vista resort on international drive. The grande vista is wonderful and is surrounded by water and golf courses. Plus when we were there, we practically had the pool to ourselves. The world center also has a AAA rate of $109 and it's also very nice.
Hope this helps.
