It’s definitely worth staying the night in Hana and continuing to explore everything you possibly can the next day. It’s an amazing journey that IMO is only partially enjoyed from a same day visit and return.
Tania and Kaua’s place is easy to find, in a good location, clean, convenient and is highlighted by easy check in/out, the kitchenette and the super great water pressure. We just stayed the night so it met our needs well. No a/c is a bit difficult for me (even in Feb) but we managed fine for just the night. It also doesn’t hurt that it’s one of the best priced stays in Hana, which is a bit pricey.
