When we first arrived at the bellhop and took the escalator down to the lobby level, I was impressed by the size of the structure inside. The large fish and dragon statues on each side of the enclosed garden area brought Vegas to mind. Everything looked relatively modern, aside from the expected historical decor.
However, our room revealed the age of the property. The hallway we were on was long and tomb-like, and felt like something out of "The Shining." We were on the same hall as the Marriott Vacation Club back-office: that is, the offices where those folks check in and out for work, not where timeshare preso's would happen. Our floor (fifth) was on the same level as the bellhop, which turned out to be convenient, because we never had to take the elevator or escalator to walk out to the parking area. Speaking of which, after our initial use of the elevator to get to our floor from the lobby level, I never was able to get the elevator from our floor - I tried a couple of times, but the elevator never came, and I ended up taking a stairwell or the escalator.
An employee mentioned that this converted property was old - I think they said something like 60 years.
Because we had traded from our Marriott Ko Olina timeshare on Oahu, I was expecting a kitchenette. Shame on me for not reading the room description, which states that there's just a mini-refrigerator.
The property is nice. The pool is massive, and having five hot tubs is great. The water slide is small - I'd think not really interesting for kids over 9 or 10. Location is very convenient to the airport, and several tourist shops, activity-booking offices, and restaurants are within easy walking distance. The beach was never crowded during our stay (spring break) - we saw a lot more people at Poipu, which is a bigger beach draw.
We'll be back to Kauai someday, but will opt to stay at a place with a kitchen.
>>> Timeshare tip<<<
We agreed to sit through another Marriott timeshare pitch, and were given the option of either the Lagoons property up the road or the Waiohai at Poipu. To go to the Waiohai, you have to have your own transportation (it's a 25-30 minute drive), so Marriott increases your gift and also gives you a day pass to that property. We went with that, because we wanted to give the kids a change of scenery. Plus we got to see Poipu and a bit of Koloa, which we might not have gotten around to otherwise. So for the effort of a short drive (and a preso of course), you can make a day of visiting another nice area and using another nice property. Remember to bring your own towels from the old Marriott.
