Depends. The continuous northbound party crowd sometimes stays up later than other folks might like. If you're in a shelter with somebody who snores loudly it can be iffy (earplugs weigh nothing. My favorites are the Howard Leight MAX with a cord. If you're a back sleeper, you can probably be less picky and go with a more rigid option). Occasionally the ground is so wretched that it'll screw up your sleeping (hammockers have different problems, but I tented, so I can't speak to that personally). Some people report shelter mice keeping them up. I've not had that experience. The foul weather rule for shelters is "there's always room for one more". That sometimes means everybody is crammed in and if one person moves, it turns into a Newton's cradle situation. Also, I don't know how old you are, but I've found the shelter floors have gotten a lot harder as I've gotten older. What I slept well enough, but not quite comfortably on on a Z-rest at 20 is now something I need a NeoAir (or equivalent) to get a good night of sleep and not wake up with lumps on my hips from the hard floor. The ground is much softer unless it's hard-packed mineral soil. Apart from those things and the occasional storm, etc, you can pretty much count on sleeping like you're dead.
