You guys. I was just back on the dining reservation site, and yes, it does say at first that you can't search/make reservations at this time. I ignored that and clicked on the actual restaurant I wanted and went down to the lower right block "check availability". I clicked on the calendar for the date I wanted, and chose "breakfast" as the time with a party of 4. Again it told me it couldn't search. I clicked the "find a table" button again and available times popped up at the bottom of the box. I chose a time and went all the way through with my reservation. I got an email saying that I have a table for 4 for 'Ohana on April 19, 2015 at 9:05 AM. Which I will now go cancel!
This can't be working for just me. Try ignoring the messages and press on.
