I take my cameras to the beach all the time and have no problems, even w/ them slung over my shoulder while I ride my bike there. Simply brush them off when you get home w/ a soft artist's brush if they get dirty, which mine never seem to do. I shoot B&W, so there's always a yellow filter on the lens (along w/ a hood) to protect things. It's a real challenge shooting only B&W there, as everyone always expects ocean photos to be in color, but it suits me.
I'm pretty sure that Freestyle sells some inexpensive single use B&W film cameras if you wish to give that a try, but seriously, unless there's a gale wind blowing I wouldn't worry about bringing your gear there as long as you wipe/brush it off when you get home. Shooting slides could be difficult if it's sunny, as the exposure difference between the bright reflective sand, the water, and the sky can sometimes be pretty wide, but early morning and late evening should prove easier to shoot.
