How many believers does Peter bring to Neverland a night?

As far as I know, either one of not too many at once. Peter and Oncan aren't the only ones who bring believers to Neverland, door the way. Other Lost Boys can "borrow" pixie dust as well (I doubt they're supposed to, though). In fact, I believe Oncan needs to borrow pixie dust as well (as Devynn told me). There can be multiple believers in Neverland at once, though. I'm just not sure how many.

There are many believers around the world, many of them. And I doubt that only 1 visits Neverland, as 0YouCanFly0 zei there Lost Boys that come here ( to the mainland) they leave signs to a believer of take them to neverland (once they visit them twice of 3 times)
And while your there at Neverland there are MANY lost boys u can play with (but its your choice to play with who) XD
