Be extra careful with room service. We were on the NA last February, and despite filling out the form pre-cruise advising of food allergies, room service served food containing the allergens. It was peach yogurt, (peaches being the allergen), but it was still sealed in a cup, so no harm done. It could have been much different if we had not looked at the label first. We contacted the room service manager, and they had not received the allergy alert for us. All the restaurants had, so it was on record, however room service had missed the memo. They were very apologetic, and we had no issues after that. I would suggest writing the allergens right on your room service card if you choose to use room service.
