We're planning on being at Disney-MGM on Monday, 10/3. We have ADRs for lunch at 50's PrimeTime Cafe at 12:55pm. We'd also like to get milkshakes (only) at Sci-Fi Dine In Theatre around 11am, which is when they open. Do you think we'd need ADRs? If we get them, would they be mad because we are only getting milkshakes? Would we even be able to get them, since Disney Dining would already have us in their system for a lunch?
Good luck. We arrived a little late for our AR there in July, people were standing 5 deep at the hostess stand trying to get walk up tables. About 10 minutes after we arrived (at around 12:25) they announced they were full till 3 PM.
