Members of the trade organisation will attend the Britain and Ireland Marketplace (BIM) in London on 28 January, just days before the newest Brexit deadline on 31 January.
The Irish backstop has been a contentious issue during the ongoing Brexit negotiations by both Boris Johnson and Theresa May.
There are more than 6,500 meetings between transport providers, travel organisers, historical landmarks, tourist attractions, hotels and tourist boards at the annual full-day event.
Both Ukinbound and Etoa will give a joint welcome at the event.
In return for the invitation, Etoa will attend UKinbound’s Annual Convention in Bristol on 5 and 6 February.
