With 3 evenings left, I'd probably rotate between stands. Since you hunted stand #2 last night without seeing deer, I'd hunt stand #1 this evening. That's really a shot in the dark since you haven't been there lately, but it may pan out. If you see deer there but can't get a shot, I'd relocate my stand a little to rehunt the area again the next evening. If there's no deer there, then I'd return to stand #2, where by and large, you seem to have been seeing deer lately.

At the the same time I agree with Dog that some in-season scouting may be in order. If you can get to stand #1 early enough to scout a little and don't find much sign, I'd ditch and head to stand #2 right away. Another option might exist if you suspect or have noticed that deer are moving through each area at slightly different times. You could hunt from the ground in the periferies of the "early" spot mostly to see if deer are moving through (try to find a vantage point), then at some decided time hustle over to the "late" spot to watch for activity. The next afternoon you can set up in a more suitable stand or blind in the location you saw deer. I hunt like that ALOT from the ground in archery season...usually several hundred yards apart between different fields and woodlots, though 1/2 or 3/4 mile might not be too bad of a stretch either.

I have an inkling that stand #2 "might" be the better bet, since you have been seeing deer there.

Good luck!
