We are having a local swim meet and we need to temporarily cover the doors to the shower/bathroom on the pool deck to keep parents and others from coming on deck. The doorway is concrete block structure, with one side of the opening being one concrete block thick and the other side being a flat concrete wall on the inside. I thought of covering with a sheet of plywood, but i think that would require putting in concrete screws and i would rather not put permanent holes in the concrete walls. Any ideas?

We had an almost identical situation in a former garage that we refinished to be an office. Our contractor suggested this and we liked the result: he installed a piece of wood about an inch out from the concrete, putting insulation between them and keeping the wood a consistent and level height - a little higher than the concrete. I can't remember if it was pink fluffy insulation or spray stuff. Then a shelf about 6 inches out from the wall - nice and level by being a bit up from the concrete and supported by the vertical wood, and there's insulation under the shelf too. The whole thing is a good looking clear pine and is well varnished.
Looking from the side gives an idea of the distance from the wall:
The shelf runs around the entire room and is remarkably useful for something so low. It hides all the lumpy bumpy aspects of the concrete and while it's not something you see everywhere, no-one has ever mentioned it so it can't be that unusual.
You probably don't need to concern yourself. The thinset plus tile should smooth out the imperfections just fine.
If you really want to remove them, you'll probably need to use a concrete grinder. But that's pretty expensive. As a "lightweight" alternative, a 4" angle grinder with a masonry wheel would knock the top off of the ridges. But it would take a lot of time and make a lot of mess to really remove much material that way.

You could try installing two expandable shower rods across the doorway. One should be shoulder high the other knee high. Mount some hooks on to a sheet of plywood. Hang the plywood on the shower rods by the hooks. Or just hang a shower curtain on the rod and place a do not enter sign in front of the entrance. This method may keep you out of trouble with the local fire department as blocking an entrance/exit is generally frowned upon.
