This tour was really great. The check-in process was easy. The tour bus was clean and comfortable, and there was bottled water available. Our tour guide, Ken, was amazing. He shared a lot of interesting information about pineapples, as well as about Maui in general. We got to sample a lot of sweet, fresh pineapple too :)
I would recommend doing this tour at the start of your vacation, since he gives so many good tips on where to go, what to see, good places to eat, etc.
One note of caution, while there isn't a lot of walking on this tour (very minimal), it was quite windy while we were there so a lot of dust was flying around - dress accordingly! My flip flops were pretty dusty by the time we got back from the tour.
