FE can be a fun activity. I've done it twice, and while there are somethings that are everyday (candy as an example) there are usually other items that are more interesting, or personalized, or thoughtful, or useful.
Don't get wrapped up in what you think you should do - peruse some threads here and possibly some other non-Dis sites for ideas. I just write down all the things I find interesting while researching -all on one sheet- then figure it out or use the ideas to create my own version. You'll find ideas that appeal to your senses, budget, skills. You do not need to be crafty.
Some cruises have an adults only FE in addition to the mixed age groups. Therefore, you are not worried about all the different ages and what to do. Also, less likely to get 100 glow bracelets! (Funny though, we've never received glow bracelets, and I travel with kids).
Good luck! I enjoyed distributing them because it gave me a reason to walk the ship and see the door decorations, and FE.
