If we cannot locate a chair where we would like to sit/layout (as we don't rush early AM to the pool) to try and grab the all important perfect chair location (sounds like a Seinfeld episode), we put our towel down on the deck near the edge of the pool and lay on the deck. We've done this numerous times and are good with it. If a chair opens up, then we'll move to it. We gave up on searching for what seemed a long time seeking out that chair and wasting time and getting frustrated. Unless things change or are enforced, you probably won't change others behavior. I'm here to relax and leave the stress on shore.
