Rumors in the AL adventures

Im using a couple of Adventure League to introduce a party of characters (half of them newbies) in a campaing.

Im starting with Secrets at Sokol Keep and find the NPCs has a lot of information/rumors bullets within the adventure.

How you manage this?

Im thinking in "conversation" and give them ALL the info throught roleplaying only but:

You role anything besides Persiation? You give less information? You give certain info depending the one they already know?

Thanks for any advice.
