First time in a grand suite on an upcoming cruise and to my understanding I can order food from the MDR to be delivered to our suite. Is there set times I have to place my order or any time during the hours they are open? Can I schedule a time for it to be delivered and do I need to be in the room at time of delivery? Attempting to maximize our time and take advantage of not having to sit in the MDR for hours.

I will be in a grand suite on liberty next month and I am finding conflicting info. I understand mixed drinks are always during happy hour but some say you can get free beer/wine all day and others say that is only offered on oasis class ships. Can anyone that's been on non-oasis class ships clarify for me please.
