Buckhead, Atlanta - HP and GH just around the corner from each other

Istanbul - GH and PH about a three minute cab ride, about 15/20 minutes on foot if you don't get lost (can't go through the tunnel that the cabs use). The PH will drop off luggage at the GH if you are out and about during the day and want to leave PH in the morning and check in to GH in the evening. Sadly, the GH won't do the same the other way around

Dubai - PH, GH, HP all within 5-10 minutes in a cheap cab. HR is a bit more out of the way, maybe up to 30 mins from GH in traffic.
