Looking at our transit options in San Francisco for Thursday through Sunday, it looks like it would be a good idea for us to get a pair of
Clipper Cards. That would let us hop on buses, trains, and ferries without having to calculate the fare each time. The auto-reload feature will dump $20 at a time onto the card as we use it, and the funds don't expire. And if I want that last $15 or so back, they'll even issue a refund less $5 processing. I'm willing to pay $5 to make getting around town easier.
The biggest question is whether there are agencies that *don't* accept Clipper, that I would need to know about. There are *eight* overlapping agencies listed - Dallas barely has one at a time (Fort Worth and Denton's systems don't intertwine much with DART). Are there any holes in the system I should know about before I order the Clipper pass? (I do see that the ferry doesn't take Clipper for the Angel Island trip.)
It looks like the first thing we'll do, Thursday morning after we get off the 6am bus from Santa Barbara, is
hop on a ferry for a 13-mile ride across the bay. (Lucky for us, it'll be early rush hour - the ferry isn't set up for casual riders.) The ferry meets a shuttle that goes to the Caltrain station or bus stop. We'll probably want to see if we can leave our bags at the hotel (it'll be to early to check in, probably), and then we'll have the rest of the day to wander around.
