Can you drop people off at the gate?

Yes, and the drop off for Peppa Pig is really close. Just can't drop off unsupervised minors

Yes there is a separate drop off area

Yes

Yes just not minors

Yes. About 100 metres from the gate

You can drop people of here over by security.

Yes there is a separate guest drop off area but it serves both peppa and Lego. So there is a bit of walking between the two
