My expeirence with the surveys...

If you take it after 8 pm EST time you get stuck on teh 24 hr rotation. It happened to me late last month, so I skipped a day and took one early the next morning and it let me back in on the once a day. I've been gone all day and doing my daily survey now nad it just dawned on me that I'm going to get stuck in the 24 hr rotation and probably should have skipped tonights and just waited until tomorrow morning to do one.

I like doing them early morning, my advice if you want off the 24 hr rotation? Skip a day and make sure you take your survey earlier in the day the next day to get back to once a dya.
