Agree with Maggie. Maybe the QSDP is the way to go for you. That way you can use your 2 snack credits for F&W food and you can supplement with counter service in World Showcase.
But if you truly want to eat something from almost every booth and do that instead of real meals, I would skip the DDP this time. Just know that you will be spending A LOT of $$$ this trip b/c the F&W stuff is expensive and costs more than the DDP.
