I'm planning a trip to the west coast, having only been to WDW before i'm completly in the dark as to where to visit on the west coast, I have some ideas of places we want to visit but coming from the tiny UK could do with some help on time and distances scales. We'd like to do DLR, San Deigo (are there more than 1 zoo's there)? Seaworld, san fransico, vegas and some national parks, Yosemite? we are hopeing to have 3 or maybe 4 weeks and are a family of 4 with 2 boys who will be 10 and 11 at the time, all your help will be so much appreicated.
