Getting to Hogwarts

Forgive ne if this topic has been covered in the past, but I am 
puzzled about sudents getting to Hogwarts on the Hogwarts Express.

In PS, when Harry sets out for Kings Cross to catch the train, Hagrid 
has merely given him his ticket a month or so previously. Harry has 
problems finding his way to platform 9 3/4 - what might have happened 
for example if he hadn't met the Weasleys?

This raises the question, how do new students know how to get to the 
train? It probably poses no problems to wizarding families but how 
did Hermione, who is from a Muggle family, know how to get through 
the gateway to the platform?
