Thanks to all for you help and input. We had a great day, with no issues.
BART parking was very scarce. We ended up parking in the reserved area a little early, but there were no other parking spots.
The parking spots are designed for little cars, not 3/4 ton trucks. Many of the spaces would have been impossible to get into.
Here's the biggest surprise. It was an hour drive from Manteca to the the Dublin BART station, and it was a 45 minute ride on BART to the Embaradero BART station. So we go to visit the restroom. It's a one holer for men, and and one holer for women. This is in a public building that a couple of thousand people will travel through each day, and they put in a restrooms that accommodate one person at a time. Really? That's crazy.
The BART ride was smooth and uneventful, it was nice to let someone else do the driving.
Had a great time in SF, took the bus tour, and we plan on going back to do the Alcatraz tour. Does anyone have a recommendation on a tour boat to use to get out to the island?
Thanks again for your help.... :)
