We are used to visiting Florida but this is our first time visiting the West coast (Oct/Nov this year) and I haven't a clue what I need to pack. I have been told that San Francisco is cool but we are only spending a couple of days here and also visiting LA, San Diego and Vegas. The majority of the time will be spent in LA. Can anybody give me an idea of what sort of weather, temperatures we should expect and what I need to pack. Hopefully not too many coats and jumpers needed...I would rather fill my cases with souveniers
