You're not going to know for sure when you make your ADR's. Your best bet is to look at the Sept. calendar (hours), hoping they're up on time and then any day that MK closes at 7pm, assume it's
MNSSHP - This does not mean each day will be, but that's your best bet. There's still a chance those hours won't stay etc., but that's really the best thing you'll be able to do. It's like that every year and yes, it's annoying.
