Getting married on a beach - woo! It's owned by the hotel we are getting married at, so they will set up and create space for the aisle and there will be a flower arch for us to be standing by, but the beach won't be closed to other guests etc.
No problem with this, it comes with the territory! However, I have just seen one photo of someone else's wedding at this venue that's got me panicked! In most photos the public seem to have set themselves up at a respectful distance, so you do see people/windbreakers in the periphery background, but this one photo has a sunbather lounging next to an ugly looking tent basically right up close almost in the arch and looking very prominent in the ceremony 
It's really shocked me that someone would plonk themselves down that nearby to someone's ceremony, and I know a photographer could photoshop them out... but it's not great to have someone right there while you're saying your vows... So it's got me wondering whether (1) I should be tasking someone like the ushers with politely ushering anyone too close away from the ceremony and/or (2) if there are any clever ideas any one can think of to kind of cordon off a few feet of area that's kind of just behind the arch so we have a little bit of buffer space?
Completely aware that I'm getting married in a shared space, and in most photos people seem to be respectful and give a little boundary space, I just don't want a stranger and all their gear squished right on top of my ceremony and this one photo has freaked me out that that might happen
