Yes, you can stay at Camp 4 multiple days. I would suggest reserving multiple days up front, it can be a pain to add days later because then you have to stand in line again. If there isn't room, you could be out of luck & have to move.
Some people sleep in line, so your best bet is to get there as early as you can. But don't be too discouraged... just because the line is long doesn't mean you won't get a spot. It just depends how full the campground is...you may or may not get a spot. If you can't get there til later in the day you probably wouldn't have to wait in line... but there may or may not be spots available.
What will you be doing while you're visiting Yosemite?
