Hi Carol,
http://www.alcatrazcruises.com/ )
The Sausilito excursion is approx. 4 hours long and departs at 9am or 2pm.
The helicopter needs approx 2 hours door to door – pick up times are usually 10am, 12.30pm & 3pm.
So, it will be busy but, you should be able to fit everything in.
Kindest regards,
Jules
