I noticed (lurking in here) that someone advised to put cellophane

I realized after reading that, that I let that happen last year and
when I got home I just turned the water back on and nothing happened.
Is there a particular danger in this. I left it the same way this
year..

Nah, not really; just a possibly unpleasant odor when you do return. Put
antifreeze in there and it should work OK and wont' evap too quickly.
