Something like 1/4-1/2 mile past the Inner Basin junction, there are half a dozen good campsites. Some are more exposed than others, so the choice depends on how much wind to expect and whether there will be lightning. The exact distance from the junction should be easy to see on a map. It feels farther than it is because I've been pretty tired whenever I reach that point. It's a pretty tough slog for newbies from either starting point unless they're very fit. Being already acclimated to altitude helps.
There's also one potential site at the first saddle, but I don't know how often people camp there. It's pretty much just a wide spot adjacent to the trail sheltered by some logs. Trail runners stash water in the logs there.
ETA: I should also mention that there's no water up there, so you'd need to carry up enough for the whole trip.
