Haven't been to Ko Olina in a while, but we bought the wristbands at Waiohai last year.
I *think* they were upwards of $25 each (there are no freebies).
There are no discounts for multiple bands.
The wristbands are re-usable (bring them back on your next stay, or use them at any Marriott that has the technology).
They program the wristband at the start of each stay, just as if they were programming a room key.
So theoretically we could use the same band at Waiohai and Ko Olina.
The wristband purchased at Waiohai had the Waiohai turtle logo imprinted on it. Sadly, they removed all of the turtle logos from the resort signage during my stay.
At Waiohai, it functions as:
- Pool wristband
- Villa access (opens door)
- Parking access
- Other access (i.e. external doors at night, gym, etc)
At the time of our visit, it did NOT provide ability to charge purchases to your room. You still give the cashier/waiter your room number and last name.
The wristbands came in two sizes. The adults in our party found the larger size to be surprisingly tight.
It is my understanding that the wristbands are passive (i.e. no battery).
If the band breaks, or the device stops functions, front desk says they will be happy to replace (for a brand new $25 fee).
If Ko Olina became all inclusive, we'd take one final trip and go nuts - just before the resort declared bankruptcy. I am shocked - SHOCKED! - that you encountered a dishonest salesperson at Marriott.
