The pools and hot tubs are lovely. Lots of waterfalls and nice features. The room itself is a little tired - bathroom especially. A towel rack is on the verge of falling off the vanity. It was a generic hotel room in a nice resort setting.
As far as the price goes... it's not $99, but $109. Also, with the Airbnb fee of $54 and the hotel fees of $114, the room price averaged $151 per night. That is still a pretty good deal for Kauai and the resort amenities made it worth it.
All in all, I recommend Peter's room.
