FE are fun. My kids love coming back to the room to find what goodies have arrived during the day.
You can make your own FE or buy one. I bought one from Ebay (shipped from Taiwan). If you search Fish Extender and/or Pocket Hanging Organizer you should get some choice. I found this Mickey Mouse one under Pocket Hanging Organizer - its similar to one I bought a couple of years ago.
There are instructions on the DIS on how to make both sew and no sew FE. You can also just use something simple like canvas bags tied together. It doesn't have to be fancy! Just make sure it is not too wide (there is only a certain amount of room to hang the FE)
On out last cruise, we all just chose one night to hand out the goodies. There was no set schedule, you worked the delivery into your own schedule. It worked out, we had something every day. Other cruises have set a schedule. Some have grouped up when there were a large number of DISers on the cruise and something like 140 FE to deliver to!! Our cruise is not that big, so we should be fine.
