We will be staying at Mauna Lani but I have read about the beautiful beach at the mauna kea. I have also read that they have a lovely Sunday Brunch. If we wend there early on Sunday could we use the beach and then go to brunch? (or vice vets, but I am guessing we don't want to snorkel after a big meal!) I can't tell how long it takes to drive there--does anyone know?
