How far is San Diego from DLR?

[cirquelover]

Please help me, I'm freaking out!

We leave for a business trip and then a vacation in four days and now my husband just called and says three/five days after we get home we have to leave for San Diego/La Mesa(?) area.
How far is that from Disneyland? How long would it take to drive? And how is the drive?

The worst part is that puts us there from May 1 to May 12 and I think that will be a very busy time. I doubt if I could get a room for the kid and I during most of that time period but I know we will be looking to go to DLR. It looks to far to drive up for the day and then go back.

Any great ideas of what to do in San Diego? I know about Seaworld and the zoo, but I haven't been there in twenty years.

Thank you so much for any advice you can give, you guys/ galsare the greatest
