Disney Cruise - Fish Extender Gifts

I'm not new to Disney Cruise but i am new to the entire "fish extender" stuff.

I think we're exchanging with 6 cabins; info isn't available yet until the 8/5 PIF (paid in full date).

I'm doing just the main exchange, not kids only, not magnets etc.

But give me some ideas!

I prefer to do a cabin gift for ease of organization. We are driving to the pier (NYC) so transporting said gifts shouldn't be terrible.

I am new to the Silhouette/Cricut world, so would love to utilize my Cameo with either vinyl, cardstock or vinyl.

I did take advantage of Shutterflys "free" magnets and made magnets with the Disney Magic leaving NY on a previous cruise and put the month/date on it.

I was thinking printable/edible oreo's with the date or pic of the DCL logo.

I bought all the Mickey jelly belly i could find in Target but i could use more if i find more.
I'll get glow sticks @ the dollar store.

I'm in a few FE groups on FB and OMG it's overwhelming
