Yes I stayed in concierge and they will help you but it's not comparable. Like I couldn't have any of the prepared apps or desserts but they could get me cheese and crackers from the back where they weren't cross contaminated. They would not cook something special. If you request something special they will try like I can only drink sugar free AND caffeine free soda and they don't mind getting something like that. If you ask for gluten free they will keep some prepackaged things on hand for you. If it's one simple common allergy they can call down to the chef and check but it's not easy. IN the morning they had lots of normal WDW foods and brand name cereals that were pretty easy to navigate (like hard boiled eggs, plain oatmeal, etc) but the snacks, apps, and desserts were not user friendly. The all day snacks were things like big jars of candy and chips so they could get me something prepackaged but no choice and had to wait for them to figure it out and find it. I loved concierge for the service and I didn't expect that I'd get all the normal food that was served so I was OK with it. My family had a great time so I'd do it again for a special trip. We've done AKL, WL, and beachclub.
