Are you doing a full rehearsal day on set to work on blocking, or just running a blocking rehearsal before shooting? Obviously with the latter, there is a bigger time pressure and you can't spend as much time working out the scene. Hopefully, the actors have already done their own rehearsals before to work out performance. It's a huge time killer when the director decides that blocking rehearsal is a perfect time to work on the content of the scene with the actors. Naturally there's always going to be a little of that, but blocking is supposed to be a technical rehearsal.
I generally ask for a blocking rehearsal first thing so the director and I can agree on coverage, the gaffer and I can discuss where to place lights, the key grip and I can figure out where to lay dolly track, and the AC can lay down actor's marks and get lens position and heights.
On a full rehearsal day, you might just have the lenses and a directors finder so you can see the shots and not have to set up the camera. A few tape marks on the floor with notes on focal length and lens height are usually enough. If there's complex camera movement and/or VFX you might have the camera there as well to work it all out.
