"Normally, I just do it on vacation."
So, is this correct? The meaning of the two words is the same, but the form one would use is different? I'd put "Normalement, je le fais seulement en vacances", which was wrong, but "Je le fais uniquement en vacances" was correct. (I might be remembering this incorrectly. I don't know how to go back to the original exercise.)
