I am planning to visit SF area for the first time
during the labor holiday (Sep. 1~3). I cannot drive by myself, but my friend can.

I need your advice and info. What is the best transportation during the trip?
Is wheelchair accessible taxi really available?
From my previous experience in LA and Boston, accessible taxi was available from the airport but it was very difficult to take this taxi from the other area (even in downtown).
I searched www.wheelchair-getaways.com where we can rent accessible van but their rate is 110$/day with no insurance plan and minimum 5 days rental during the labor holiday.

Any suggestion? Thank you.
