Hello, we would like to drive east out of Waikiki to see the Makapu'u Tide Pools and maybe the lighthouse, go on up to Kailua and 1/2 day kayak rentals at th beach there, then drive up and around the coast to Hale'Iwa, then back to Waikiki. Is this too much to do in one day? How big are the waves in mid-March on the North Shore? Are we likely to see any whales on this itinerary? Alternative suggestions?
