We're from Australia and staying 5 days in SF. Looking for family accom? What about the Grosvenor Suites or Hotel Union Square. Can't find any 2 bed suites or really even many hotels without booking 2 rooms. Aussie $ still at 68cents so 2 rooms get very pricey.Coming in February so do we need to book Alcatraz tour? I gather bike riding over Golden Gate Bridge doesn't need advanced booking.Thankyou for help.
