No where to go (Riverside)

I am looking for a place where I can stay for 1 week at most.
I've had enough of the lifestyle I have been living and I have decided to admit myself into a rehab facility in Vista, Ca.
The place is called Green Oak Ranch in case you want to look it up.
I have a week before I can arrive at the Ranch and start the 9 month program.
Can anyone offer a place to stay for a week please.
Dave.
