Marc the Robben Island tour leaves from the waterfront. Cannot remember exactly where (it was about 11 years ago now) but we walked there from the Cape Grace. The boat normally docks right in the waterfront near the Table Bay Hotel (close to Baia restaurant). So all of that is close.

Marc, I do not think they WILL offer any tours that day at all. The message reads as follows:

As shore excursions to be offered in this port are not yet confirmed, below is a list of those offered previously. We make every effort to have excursions finalized at least 240 days in advance of sailing, and often sooner, so please check back regularly.

We are past 240 days and I really think this is just a standard message to the website if it is a port day and no tours have been posted yet. A self populating message in their system. They should change it to say NO TOURS it is very unusual to have a port day with no tours but also unusual to arrive at 4.00 pm.

You note they do not have any "examples" of tours either. The actual tours are all there for the next day. I think all the tours for this trip are posted and
nothing else will be coming.
