This question has a two part answer.
1. If you were able to scout this ground and had access back in late winter/March, then the time to have hung a stand/ladder (or at least make the spot ready), would have been then. Winter scouting reveals almost all of the sign from the past season, and the trails, beds, rubs, cover etc. would have been like you would see during mid to late season.
Unless there is a drastic land use change, then this should still be a good spot. The advantage of placing a stand at this time, is that it also gives the area 7 to 8 months to "settle down", and for the deer to get accustomed to any minor changes that you made.
The ground that I hunt, I have been on for at least a decade or more, and I can usually count on the same areas from year to year, so I basically stay out of the woods, or at least the denser areas that I will hunt, until I start hunting.
2. If the above option isn't viable, then do as much of your scouting via aerial photos and maps, and maybe a brief early/mid summer excursion or two, but DON'T hang stands or clear trails. Wait until the day before, or even the day you want to hunt and go in, cautiously, and have at it.
I, like others here, have had a reasonable amount of success with this "lightning strike" approach, but it usually only works best on private, or some other limited access ground. If 4 other guys are doing the same thing in the immediate area, it kinda takes all bets off the table.
Part of the reason why this method works, isn't so much because the stand site itself is new, but because you have only gone in and out from the stand once or twice.
Constantly moving to and from a stand, especially if you are one of these "hunt until 9 or 10, come in and have lunch/nap, then "scout" the area, then go back for the afternoon hunt", will burn an area out faster than putting a subdivision on it!
If you DO have to move in and out during daylight, it's better to vary your travel route, so you don't go the same way twice.
During firearm season, and many times during bow season, I will stay out all day. I usually get my "woods nap" (the finest kind of sleep known to man, by the way..) around mid-day, but the difference between sleeping in the woods and back in camp, is that when you awake in the woods, all you have to do is pick up your weapon, and you are hunting again. You are THERE...no walking in to make it easier for the deer to pattern you.
