If he lets you sit all day then do it at least one of the days. Deer will sometimes pattern the hunters and if noone hunts at noon that could be the magic hour. Something tells me that he has a good handle on the situation and since he doesn't allow walking in the woods patterning the hunters is harder for the deer.
I know from fishing if a guide says to use a certain fly or lure you'd be foolish not to. He knows his home waters better than you do.
Maybe he can stagger his hunters, taking one in for lunch while leaving you in the recently vacated stand. If the deer indeed have the hunters patterned you may be in luck. He may also have this system in place cuz it is easier for him rather than having everyone do as they please. Good luck on your hunt!
