If you look at the bigger picture, say look at your average over a week instead of daily, moderate holidays can fit in fine with no big changes. Maybe eat at the lower end of the range (not under it, just on the lower side) for a few days before or after if you're concerned about it. Assuming you aren't totally over indulging, worst case is that you will lose less or maintain for a week. In the grand scheme of things, that isn't really that big of a deal.
Have fun in France! Im sure you'll get lots of exercise there, just doing daily stuff.
