It sounds like you have some legitimate concerns that you ought to pass on (concisely and politely) to guest relations, just to let them know your experiences.
I did just this regarding my problem with ships security letting my 16 yr old daughter off of the ship by herself and carnivals respose went like this "your comments regarding minors getting on and off the ship, we rely on the gaurdian or chaperones of minors onboard to provide supervision"
Now tell me if I'm wrong but this basically says it your fault not ours....My child and I were unlucky enough to get seperated in the crush of people and I was in the line just several people back but the point was that we were not together and they did not check for an adult with her eventhough Carnivals guest services in Miami tells you if you ask that noone under the age of 18 that is not on a carnival supervised shore tour must be accompanied by an adult when leaving the ship
So I never mentioned the shut up of the fact that room service was an issue I made them aware of the biggest problem I had on board but its a simple matter of its your child and you should have kept an eye on them regardless of the fact that they were responsible for at least making sure that there was an adult in line with them somewhere..
