Snaefellsnes: tours on Saturday ?

Hi,
we are looking for a guided tour to Snaefellsnes peninsula on Saturday May 15.
We don't manage to find one on the web with the classical parties: they only do it on weekdays.
Any suggestions are very welcome.

Try companies like www.superjeep.is www.atours.is www.gotraveliceland.is

Do a bit of reading about the area, rent a car and go by yourself.
