Not quite the same, as Zara is a bit younger, and we have always had issues with sleeping at daycare....but my two cents:
Our daycare recently changed to us having to bring in cot sheets for our los. They have told me that since I bring in Zara's sheets, she is really easy to put to sleep now, compared to before.
I try to make all meal times at home match daycare. The nap times very greatly, no so much in start times, but definitly in how long she stays asleep. But I think that by keeping the routine as similar as possible, she just knows what is next.
Having said that, I am always on to them about cue watching, cause that is what I do at home. If there is some reason why I want them to do things a little different for a few days, they do try to accomodate me - I say - recovering from illness, needs an earlier nap, or whatever, and they do try, but that is not a permanent solution.
