I purchased it right before we left, but I agree with the previous poster, about three days would be safe. I will make a clarification. If you want the printed photos vs. the CD it is the same price as the the CD. I made the mistake of purchasing the "All Prints" package instead of the CD, and it was no problem for them to change, with a little lead time, because it was the same price. Yes, if you want to add the printed photos to the CD, it is the same as adding them on onboard. So, don't fret if you want to add the prints later.
