I have not made the trip myself, but have gone from haro straight to PT.
Look at weather forcasts up to and including the day you leave. Along with currents. Generally speaking you should have a reach going across, so this should be faster than a point or run. On the other hand, choose the wrong day and time, you have 10-15' rollers going thru.
I'd give it 2-4 hours depending upon your boat speed, motoring vs sailing in light winds etc.
