Yosemite march need advice

Hey,

I will fly Poland -> San Francisco in March for GDC, and stay after for a week.

Been climbing for couple of years, including multipitches, doing up to European 7A on boulders, 6C+ leading.

But I have no idea about big walls, or crack climbing ( no cracks in Poland :( ).

Always dreamt of Yosemite climb. If its not possible for me, I will go do Bishop for boulders, but if possible I would love to try some bigger wall following the lead ( I know there is no chance for a lead by now ).

Any idea on - should I even think about this? Do you think its possible to find someone who is confident enough and doesn't have a partner that would follow him just for belaying? Should I even do it?

Open to any advice.
