I always like specialty beverage containers (including at bars/lounges like Trader Sam's) and this trip I got my young cousin who's a Star Wars superfan one of the Millennium Falcon popcorn buckets. Generally any containers with food or drink can be purchased with the food or drink provided separately so they won't get dirty. I'm also a big fan of gifting magnets, the character shaped pens, and themed drinking glasses (e.g. lands or specific rides). I'm not sure what family members you're gifting for, but I'll sometimes get my mom a WDW frame and put one of my ride photos in it. Just some ideas to help you get started!
