Consider the operations within a modern urban transit hub, which integrates train, bus, and local metro services. The hub offers two primary ticketing options: $$Family Booking$$ and $$Solo Booking.$$

$$ Family Booking is exclusively for families traveling together. A designated family head $($could be a parent or guardian$)$ is responsible for managing the bookings for the entire family unit. This includes selecting seats together $($if applicable$)$ and ensuring any family$-$specific accommodations are arranged.

$$ Solo Booking caters to individual travelers, including adults, minors without guardians, and travelers with special requirements $($such as those needing accessibility accommodations$).$

All travelers must undergo a security check before proceeding to their boarding area. Additionally, travelers have the option to utilize luggage services, which include $$Luggage Check$-$in$$ for those with baggage and a $$Carry$-$on Only$$ process for those without any check$-$in luggage.
