This is a great hotel to stay at for a couple of nights to access the boat trips leaving from Lahaina or if you want to explore Lahaina for a couple of days. The hotel is right across the street from the entrance to the boat dock. We took the ferry to Molokai, so stayed at the Pioneer Inn the night before the ferry ride, as well as the night we returned to Maui. The location of the hotel couldn't have been more perfect - we had to be at the ferry at 6:30 a.m. and all we had to do was walk out the front doors of the Pioneer Inn and across the street - about 50 feet, which was great because we were loaded down with all our luggage plus several bags of groceries for our stay on Molokai. The day trips to Lanaii, Molokini & Molokai leave from here, as well, so very convenient.
The hotel itself is historical so it has lots of character. The room was on par with Best Western standards, so it was very clean and quiet, the bed was comfortable, there was air conditioning so we could recover from the humidity, a fridge, a wonderful, large lanai (deck) that we could sit on and enjoy listening to all the birds in the large trees on the property, as well as watching the sun setting on the ocean, as it peeked through the trees. We didn't hear any noise from outside, the room was very quiet even though there were several other people staying on the second floor.
The hotel is also only a block away from the stores on the main street of Lahaina, as well as the humongous banyan tree in the park. Restaurants, including the amazing Pacific O, are within an easy 5-minute walk. The Old Lahaina Luau is a few blocks away, as well (best luau on Maui).
The staff were all very friendly and helpful - the best front desk staff we encountered anywhere in Hawaii! They allowed us to pay a small fee to park our rental car for several nights while we traveled by ferry to Molokai. The car was safe and sound when we returned.
Parking is off site, but it's just down the street and we didn't have any problems parking there. We were able to drive the car up to the front doors of the hotel to unload/load our luggage.
We didn't eat in the restaurant/bar but it looked like it would have been a fun experience - sitting by the open windows and looking out at the dock/water.
There isn't an elevator, as far as I know, so it could be a bit of a struggle (for some people) getting all the luggage up and down the stairs. less
