Search from an Train/ Bus/ Hotel/ Lounge Buddy?

Hi
Does it is possible to add an something for People to search for someone who sleep in the same Hotel, stay in an Airline Lounge (on the same Day), is at the Airport at the Same Day, have the same flight?
If not does your "Platform", Plugins allow it to add the feature for an good Value?
If yes if would write an Factsheet what I imagine in my sic mind. :laugh:
Thanks
