Fish extenders on Disney Magic

[macri69]

Hi, I'm new to this site and have just signed up. We have recently booked a cruise on the Disney Magic and have read up on fish extenders. It told me to go into this forum where I can participate and find other travellers on the same cruise so I would know how many families will be joining in the fun. Can anyone help with this as I can't find it anywhere? So excited for our first Disney cruise, just can't wait for all the fun!!! Thanks, mary
