We can't remember if we made this clear already, but just so everyone is on the same page — there will be anti-apparition wards up on the Potter house where the final battle takes place to prevent people from leaving. They'll be able to apparate in but won't be able to apparate out.
And as another reminder: the deadline for these logs is 11:59PM on January 26th!
Please don't hesitate to ask if there are any more questions!
