Of the two, I would definitely recommend the Waiohai as it is a newer, smaller resort, sits right on the beach, and the amenities are terrific. My husband and I stayed there with another couple last June and loved it. We also visited the Kauai beach club during our stay and found that to be too big and impresonnal for our tastes. It did seem to have more variety of restaurants and a much larger pool, but, given the choice, I'd go back to the Waiohai.
Stayed at Kauai Beach Club in 2003 on first trip to island and ended up buying 2 weeks at Waiohai. Bought another week every other year last year. This will be our 6th year back on the island and 5th at Waiohai.
Kauai Beach Club & Hotel are as described, a little worn around the edges but appeals to some as we have friends who bought there many years before we bought at Waiohai and like the atmosphere which is a bit more lively than at Waiohai. The pupus on the veranda are an inexpensive when compared to eating out at a restaurant. You can make a meal out of them easily. We really enjoyed sitting on the veranda near the piano player while watching the rain from an evening storm.
We like the quieter atmosphere at Waohai and feel it is more family oriented. Villas are magnificent and with full kitchen, guest bedroom and bathroom along with in villa washer & dryer you have all the convieniece of home. Koloa town a quiet country village atmosphere as opposed to Lihue.
The restaurant at Waohai is just OK but we eat in a lot and have some favorite places within walking distance so not that big a deal.
No matter where you stay the fact that one can get anywhere on the island N, S, E or W in a relatively short time is a plus in my book. It's a small island but full of Aloha spirit. I also like the fact that there are no freeways and the maximum speed limit is 50 mph on county highways.
That all sounds like our story....stayed at the Beach Club...got a couple weeks then at the Waiohai! Love my Waiohai....and the gang at the Honu Bar....love them! We usually end up doing a stroll around the the Beach Club with our "guests"....have to do a trip to Duke's and then show the folks the BIG place. I would not diss the Beach Club and its rooms. A totally different experience. More of a hotel experience with their nosomuchacondo experience. Some people like the big and the glitzy feel.
