The place is very nice and just a nice 5-10min walk along the green-way to both Shipwreck's Beach at the Grand Hyatt on one side and on the other, Brennecke's and Poipu Beach toward the Marriott and Sheraton Resorts. There is a small pool near the tennis courts but it's not very impressive at all especially in comparison to the surrounding resorts so we didn't end up using it and just hit the beaches instead.
If you are looking for this place using Google Maps, i suggest searching for
"2381" and looking for the parking lot in the back. For some reason, Google Maps of the actual address (2387) will put you on the cross road instead. Also, the place is on the second floor, so stairs are involved, in case that would be an issue.
There's lots of snorkel gear, beach chairs, an umbrella, beach towels, boogie boards, inflatable tubes and even a cart to drag it all in. Soap, body wash, shampoo, conditioner, lotion, laundry detergent, dishwasher pods, extra paper towels and toilet paper were also all provided. The only issue (hence, minus one star) was that the A/C died after our first day which made our nights rather uncomfortable. Hopefully, it'll be resolved by the time you are reading this.
