All the time! I have a picky autistic son who only likes certain snacks that are sometimes hard to find even in a regular grocery store near WDW. I check it with our other luggage and it just gives me peace of mindYou pack a jar of PB? I was considering doing that but didn't know if I could bring it in my checked luggage. Can I pack Jelly too? My kids are picky about the brands as well and I wanted to bring strawberry uncrustables as I found out the resorts only have grape. Uncrustables are good for 24 hours at room temperature so I thought I can bring a suitcase of just snacks. Has anyone done this?
