Oh ladies - this is so exciting! I wish I lived in a HUGE house so everyone could stay there for a SE slumber party! But back to reality for me
On your list Jen... The North Druid Hills location is most centrally located and in a pretty safe area. It is within the city limits and about 6 miles from downtown.
As for the Marrow location... I wish I could say if its safe or not, but I've never been... I can say I don't recall ever really hearing anything bad reported in the news from Marrow.
It is about 15 miles from Atlanta.
I hope this info helps some.
What else can I do to help?
