Yes that one. We had quite a few occasions of them with their fans causing blocking walkways, and once when they pretty much barged past my child and I while filming, not looking at where they were going. I have a feeling our cabin was close to theirs as we couldn't get away from themIf they’re talking about the UK bank holiday cruise to La Rochelle (I was on this cruise also) it was less Adam and more the hordes or Adam and Gary fans on the cruise constantly crowding around them and causing scenes wherever they went. There were a LOT of vloggers/influencers on that cruise plus This Morning or Loose Women etc so there was just so much filming around the ship it was quite unpleasant (and the TV crew were extremely rude)
Rightly or wrongly, I feel like if you're the one attracting crowds they you should be responsible for managing them to ensure they aren't blocking corridors or the deck.
You're right about how unpleasant it was, we managed to miss the TV crew but the vloggers were everywhere.
