We paid for the DDP last at our stay in the Beach Club Villas, it did make us try some resturants that we'd never got round to eating at. We did 'save money', in that the cost of the food we ate was more than the cost of DDP, but there was an awful lot of food to eat. Our trip was 14 days, so we had to have the plan for all 14 days - it would be much better if you could choose a number of days to buy the plan for. I've just had a thought, in theory you could make two 7 day linked reservations and only buy the DDP for one of them!
A couple of thoughts on DDP. You will need to make ADR's for your table service meals and don't make too many buffet reservations - we did, thinking we could just pick the bits we wanted to eat, rather than ordering something specific, but we got fed-up of seeing the same options on the buffet. The Resturant Marrakesh was the best meal we ate (much to our suprise), we had the Kings Feast and the actual cost of this meal was more than the daily cost of the DDP. The 'worst' meal we had was the buffet at the Holywood and Vine (see comments above on buffets!) and the most disappointing was Le Cellier - we've eaten there before a couple of times and loved it, but I think both me and DW made the wrong meal choices! I ordered the Salmon which came on a cornbread 'cake' which was about 8 inches in diameter - now I like cornbread, but there was way too much of it.
