Thanks for your comments, Steve, and I do enjoy your informative website! Our stay in Rarotonga was a little disappointing but certainly not a "trip ruiner", and my mother actually liked the location and didn't want to move (even though I seriously thought about it). She's not very picky, and the Polynesian is such an enjoyable resort that it would be hard not to have a good time there.
We loved the beach and the tropical landscaping, and my daughter loved the pool, of course. We also enjoyed being able to rent the "water mice" in our last day.
Obviously, most of our time was spent at the parks, but we did have to spend one whole day in the room with my sick daughter. Even though housekeeping service was just about average, I will say that the Housekeeping Manager, Jeff, went out of his way to bring her a stuffed Minnie and autographed photo of Minnie when he found out she was sick. (And housekeeping had to change the bed linens twice, and they were very nice about it.)
Once again, thanks for all your helpful info and website, Steve!
