Maui, the four Seasons.

They don't have palapas in Hawaii

What kind of hotel are you seeking (besides "perfect")? Do you want a large resort property? What kind of price range? Does it need to be beach-front? With a view? Condo or single hotel room?

Are you willing to rent a car?

Also, what time of year? And how many nights do you have? That will help determine if you can do more than one island. You will need a rental car pretty much anywhere outside of Waikiki.

That's incorrect. A quick google search shows that Sheraton Maui has some palapas. I'd imagine that isn't the only hotel in Hawaii that has poolside or beach palapas.

OK ok... I stand corrected. Again. By tom42. I knew I should have said they are not as common, you don't see them on every single beach, like you pretty much do in Mexico. And palapa is a Spanish word so they may be called by a different name. Better? Now can we get back to suggesting an island?

With only 6 nights you want to pick only 1 island. You have chosen Oahu, if you want to stay at Disney Aulani. Sounds like your trip is pretty much planned then!

What more can we help you with?

I'd like to know why you think that Disney property is the perfect one for you. I ask because there may be others elsewhere that are similar and perhaps even better. Could your current choice have to do with the fact that your son and family will be there also?

If you choose Oahu, I'd recommend staying right on Waikiki Beach at one of the iconic hotels there like the Moana Surfrider or the Royal Hawaiian. There used to be Sheraton Hotels, now owned by Marriott. So if you have any Marriott points, this would be a good place to use them. Personally, Kauai is my favorite island - we spend a month there every winter. Waikiki is a lively area with lots of options for dining. It's in the midst of a big city - Honolulu - so very different from the other islands, or even other areas of Oahu.

Note that the Disney Aulani is locate in Ko Ilina, a purpose-built resort community. It is located away from Honolulu, so if you want to visit places in Honolulu, you'll need to rent a car. Decide if that is what you want.

How old are your son's children?
