You should also know that most restaurants (including the country clubs) do NOT take reservations, even off season. In a few cases, they might make an exception for 'large groups,' but it'd be rare.
That said, some of the 'better' ones may accept reservations for Mother's Day, being as it is special.
It'll be a gamble, in any case. But, be thankful that a great many folks have gone back north and those of us who hang out here year around can get in at a time when we want!
