I managed to get to the mall straight after the morning session and got my new extra luggage bag. Next task was to get back to the hotel room pronto, pack, and check out. Hopefully that would be before noon. There is another session going on then. My transport from the hotel to the airport would be at 2 pm. Should have plenty of time.
I might have to buy some titbits at Heathrow later. As for now, I should be done. More on the Atlanta trip here.
