How much of an issue is it that we do not have reservations for our dinners for a family of 4? My DH is I. Paris now & I have given him a list of restaurants to make reservations at and he has not been able to get to it because of his schedule. I don't want to rack up international charges on my phone so I have not. Nothing I'm looking at is high end or big $$ places. Will it be a big problem?
