Kauai can be an expensive place in terms of accomodation if you haven't booked anything in advance (mainly "vacational rental" as they call it).
So this is a small hotel, well located in Lihue, at a walking distance from a beach that will suit kids.
Staff is great, very helpfull and attentive, free use of small boogie boards or other "beach" equipment that you could need.
cons : curtains can't manage to keep the room dark, and wall are not that thick...so you could expect a bit of nois in case of a late or early shower from the room next door.
Stiil a very good deal for the area. Would recommand it, but just a making it your "night base" (i mean : don t think spending anything else than the night time..)
