I'm getting quite anxious about the safety issues that seem to be coming up regularly here on TA. I'm going to Paris with my husband who's got a conference there, so he'll be stuck at the conference the whole day 9-5pm and I've got the whole day to occupy myself. I would love to go shopping during the day and only do the touristy stuff with him in the evening. I read that the affordable shopping would be near Les Halles, Rue Rivoli area. So how safe is it for me to wonder around that area by myself during the day? My biggest worry is not being to speak any French and being alone! Is it more advisable to stick to the big department stores instead??
