Getting Airbnb hosts together

[Fran16]

I run my Airbnb in Margate, Kent,  UK and my local council wants to connect with hosts in the area and explain how the tourism office can help them and tell them about the local Kent accommodation scheme.

We would like to invite all hosts in the area to  get together.

Any ideas about how we could do that - given that we dont have their addresses?

Thanks

Fran
