You asked if Thursday still works, and yes, that is probably the easiest day for me.
I can get there a little before ten so we have time to go over the details without rushing.
If you want, bring the printed notes because it helps when we are looking at the list together.
I checked the room near the back and it should be quieter than the one by the kitchen.
Also, I spoke with Nina, and she said the plant cuttings are ready, so if you still want some herbs for the window box I can carry them over.
For lunch, I think something simple makes sense since we may run long.
Maybe soup, bread, and fruit, unless you were thinking of that pasta salad again.
The only other thing is parking, since the side entrance fills up early.
Try the lot behind the library and walk through the small garden path.
That route is shorter and has more shade in the morning.

You asked what time we should start on Saturday, and I think an early afternoon plan would be best.
If we meet around one, we can set everything up before everyone else arrives and still have time to adjust things if needed.
For the table layout, keep the shorter one near the window and move the taller chair to the corner so the path stays open.
I also remembered you wanted a few calmer activities for the younger kids, so I can bring the paper, colored pencils, and that box of puzzle cards.
For food, I would skip anything too complicated and just keep a mix of warm and cold dishes that can sit out for a bit.
Miguel said he is happy to help carry the folding chairs if we remind him the night before.
If the weather turns breezy, we can use cloth clips to hold the napkins in place.
That should cover most of it, but send me your list if you want me to review anything else.
