Hello Mossman,
I only ordered room service once late evening. But it is 24hr service, with breakfast from 6am, fruit trays and the like any time. Pretty sure you can call the night before and have it delivered. The preferred section has a concierge, so it should not be a problem.
Bottled water is only available from the mini bar or room service. There is a small shop by the Co Co Café, that sells bottled water, Gatorade, etc. Cheaper to tip the fridge stocker. But it is nice to have extra when you first arrive.
Hope that was some help. Have a great trip.
Cobra269, I herd first hand a number of people grumbling about room problems.(Many being valid complaints) They seem pretty short staffed, there were a few unhappy people. We might have just gotten lucky with our room. And with the deal we got I could not complain to much.
