Lightbrite,
Inside Disney, the double-sealed frozen meals heated in a microwave are likely the best you’ll get. I haven’t been to Orlando in 5 years, and I haven’t been to Disney since I was a Florida resident over a decade ago. There are a few kosher restaurants around, but the turnover is fast and the hashgachos can be confusing, so I cannot recommend a specific place. I am familiar with the Miami-based ORB, and the RCF is Chabad’s north and central Florida rabbinical organization, but outside of them I know nothing. I miss Ole Gourmet in Maitland – it was a repeated stop for us during trips across the state once upon a time. If you want to go beyond the microwaved double-wrapped airline meals, you should probably look into getting meals from restaurants outside of Disney, or bringing in your own food.
