From my experience at poolside grill on Regal and Caribbean Princess I found them very sensitive to my needing to be gluten free. I hand them my GF roll and they place it in a separate area on paper, change gloves, obtain new knife etc. I am sure that there could be some less than attentive staff but I watch closely and have not had an issue. Glad to know I am not the only one who brings their own rolls on board (as well as some GF cookies )
