4 of us visiting Dec. 27th two of whon never been to Maui. Arriving 9am at Kahului airport and will rent a car. My plan is to show my friends as much of Maui in one day as possible. We have dinner reservations for 6pm at Mama's so obviously we would end up there at end of day. Is the road to Hana and then to Haleakala too much in one day and if not can you suggest where to stop for good eats from beginning til end of day? Much mahalo from da bottom of my heart! All suggestions/ideas appreciated!!
