Definately let the special diets/dining people know ahead of time what the allergies are and they will send you plenty of info. We just returned last night from our first trip with food allergic children and it was so nice to eat like normal people. The people in your group will no doubt enjoy this perk as well. We ate at a buffet and the chef came to our table and provided us with options, made the meal himself, then walked it back to our table. We had been a little nervous about CS meals too, but by the end of the week we were really tired of having our cooler, diaper bag, medication bag checked at the gate and left the cooler at home. CS managers were knowledgable and also prepared the food themselves. Snacks were a little tricky- lots of ice cream treats made by Nestle and all are made on shared equipement with peanuts so were off limits to us. We did find many places with fresh fruit which was great. Take your own favorite snacks and save money if you are unsure.
