Well they are typically offered at different times of the year so the first questions is WHEN can you go? If you can only go during the May promotion, then it is a savings off of your trip. As far as Free Dining that has typically been offered in Spetember so if you can go then, this is a great deal and a wonderful way to trry out some of the great sit down restaurants that Disney has to offer. If you, like me, have the option to choose between the two there are also a bunch of other factors which may help you select a time frame to go including but not limited to the Flower and Garden Festival in May, Potential for hurricanes in September, personal scheduling, financial situation, etc. Hope this helps!!
