Thanks for the help guys. I actually reworked my planning for this trip and realised that I have 7 hours in LA at the start of my trip so I will hit the Santa Monica store rather than Chicago - I was desperately trying to work out what to do with 7 hours in LAX - now I have something marginally less painful
Now deciding whether I want to do the mileage run or not.... its only about 3000 points...
