We're less than 30 days out! I'm getting ready to make our Be Our Guest Lunch pre-order and realized I have a ton of questions We are on a reservation with my parents, who are not on the Disney Dining Plan, but we are. How will payment work? This is sort of a general question--can a kid's meal credit be split for two snack credits? I think my daughter will want a soup instead of a kid's meal and we want to try cupcakes, so it seems like we should try and do that if we can. Can you change your order in advance once you've placed it online?
