@AV8rix I see people holding the large HAL banner, too, when we leave FLL and always make a point of waving at them. My sister thinks I'm a dork and DH has no idea what I'm talking about, so I wave double to cover theirs, lol. 🙄
I have wondered if they hold up banners for other cruise lines, but since we're special, I've not pursued an answer. 😊
