While Poipu remains overcrowded and over-hyped, the Marriott Kauai Beach resort was less crowded, with the biggest swimming pool on the island (surrounded by hot tubs you can swim to), and has a nice beach front. The location of the resort is great because you can get to most locations of interest within 30-60 minutes of driving. We really loved that the pool was truly a fun relaxing place to hang out, filled with families who were happy and content. The resort itself is aging a bit but it has one of the best gyms I have been to: lots of very nice LifeFitness weight machines, a Smith machine for squats, lots of nice treadmills and stationary bikes, and a huge adjacent ope room dedicated to yoga + other floor exercises and it has a big collection of dumbbells and kettle bells with a few benches....nice! We just had a really good time there and would definitely come back.
