Default Fermentation Temp Stability

I am in Florida. I don't have a fermentation chamber. I keep my carboy (bucket) in a tub with water. I rotate out frozen 2 liter bottles in the water. But I still gave to go to work etc. so the temp may fluctuate up to 10 degrees from when I leave to when I get home. However, it never gets above 70.
My question is...
I'm using US05
Is it better to have a stable temp above 70 or a fluctuating temp 70 and under?

How far above 70? Also remember that the beer will be warmer than the outside water is because of the yeast activity. For me it's about 5 degrees warmer.
My opinion is that it's better to keep on icing with the fluctuations.

It would be around 74 ambient. So way too high! I just wasn't sure how the fluctuation was affecting flavor.

From what I've read or been told it is not ideal, but I do it too while at work.
