Festival fold

Hi, I am working on a file for Summer festival in Abu Dhabi, what do they mean by the sentence in bold please?

Abu Dhabi National Exhibition Centre (ADNEC) is SummerFest’s family-friendly edutainment hub with world-class shows and exciting international acts, while a dynamic line-up of Arabic concerts, comedy nights, theatre productions and celebrity-driven sport acivities will roll-out at Yas Island’s du Forum – bringing our entertainment destination into the festival fold.

Thank you

A fold is where sheep are kept overnight or for shearing. Everything in the fold will be the same thing - sheep.

Figuratively, "the fold" is a single, recognisable category of things (or persons). Thus: bringing our entertainment destination into the festival fold. = bringing our entertainment destination into the same category as festivals.

Some day you may receive an invitation to become a moderator on WRF. When you do, and if you accept, you will receive an e-mail which says "Welcome to the fold." and you will become part of the fold of moderators.
