to develop a system that functions as a:

A new account for users already onto other social-networks where here the user eventually filters his network by their common interest and shared events.

This functionality should suit some entrepreneur's own idea of a travel agent.

A system that connects users with businesses like hotels and flight ticketing, and enables the users to transact. The term 'third-party' suggests that the site shall function as a middle-man for a business with such policies.

###Deliverable One chain-process shall be:
travel inquiry > quotation generation > booking ...
I insist (to myself, for now) that this chain should end upto ... > feedback.

Taking into consideration that each of these site functions can be considered as an Application. Hence, the project may develop into a mix of these objectives.
