The only issue would be that some trub/yeast will settle out in those few days. This would be a good thing except that on bottling day, you have to add some sort of sugar for carbonation, which has to be mixed into the rest of the solution evenly to ensure equal carbonation of the bottles. Chances are, you'll be stirring the bucket to mix in the sugar, which will also re-mix the trub into the solution, which will go straight into your bottles. If you can stand to wait a few days, then rack into a bottling bucket and bottle immediately, I'd go that route, otherwise you'll end up with quite a bit more sediment on the bottom of each bottle than is desirable, which could lead to eventual off-flavors and just a general unappealing haze to your brew.
