We will be there the first half of March. It looks like there are 30 beaches and we only have 9 beach days. We would like to split our beach time up by bringing our own picnic lunch half the time and eating at a beach restaurant the other half. On the picnic days, we would like to find secluded beaches away from the action (we have our own chairs). What beaches would you suggest for the picnic days and which restaurant/beach would you suggest for the other? We have two teenagers who like to play in the waves, are there beaches with more surf than others?
