Harry will be there... will you?
Albus Severus Potter's first year at Hogwarts. And Rose Weasley, and Scorpius Malfoy's first year as well. And their families will be at King's Cross. Which means a bunch of wizards and witches you have to meet.
(and with some luck you might catch a glimpse of Teddy Lupin and Victoire Weasley snogging)

((This event is not a "real" event, it's just for fun to simply celebrate our love for Harry Potter online or wherever you are! But we do not take any responsibility in case 23k people show up at King's Cross! Have fun everyone! ⚯͛ △⃒⃘))
