I'm not in the hospitality industry so it's hard to randomly connect on LinkedIn without mutual connections. I'm looking to connect with hoteliers or those in hotel management about a product I'm developing. Facebook groups have also been a dead end.
Are there other avenues to connect or at least reach them?
Even third party sites that connect you or validate for you?
There are 5 hotelier magazines in the USA. There are at least two hotelier associations (AH&LA, AAHOA). And there is at least one hotelier convention. These are your primary avenues to communicating to hoteliers. There's also an independent research firm that only deals with hotelier data (Meinrad).
That you don't know any of these and you're trying to break into the hotelier industry is very worrying. Where is your basic research?
