Masha'Allah we have fatwas coming in left and right without knowledge on the proper ruling of Niqab in Hajj.
The Hadeeth does not say 'do not' wear Niqab. It translates to the cloth not touching the face of the woman. And for those who love Allah and His Shari'a have figured out a way of concealing the most beautiful part of a woman's body i.e. the face and not letting the cloth touch their face at the same time. Alhamdulillah.

Also many scholars recommend that the women should perform Hajj only once in their life time because of the fitnah that is caused because of them.
