Wife & I stayed a week on Maui for our 30th back in 2016. We loved it. Neither of us would do the road to Hannah again - PITA drive (I drove our rental car) but there were some beautiful sights - too bad my eyes were glued to the road - you couldn't take your eyes off of it for a second! The drive to the summit of Mt. Haleakala was awesome, & really not that crowded. We found some great restaurants & they were all priced quite fair. Went to a grocery store to get a find Hawaii-grown pineapple - they were all from Costa Rica!
