Great instincts! It would be less the entourage and more an accredited travel agency with established reputation. And absolutely correct that the skip should be auditable and intentional - and having support at the provider level for this makes this more auditable, not less.

This. Left unchecked, an entourage around a fake "celebrity" can get pretty far.
