I'd probably just eat towards the upper end of your calorie range, and if you're feeling low on energy or extra hungry, then you could add in an additional snack if necessary. Since it's only a temporary change in your activity level, I probably wouldn't adjust your calories burned goal at this point.
Hope that helps,
