I made my dining reservations yesterday at the 180 day mark (at 6 am too!), but I could not get a reservation for 4 on my 2nd trip day at Narcossee's even though there appear to be available times the day before and the day after but of course those won't work. It's a Sunday in March. Am I missing something?
It's possible the restaurant didn't release anything for that day. There may be a scheduled private event on that day.
What time of day are you looking for?
