I can see the hours limited for safety, but I've stayed at many Marriott and DVC resorts, and they are pretty similar. The grills at the Marriott are gas like Aulani. Marriott does have studios, and you can book all the rooms on a cash basis, just like DVC.
The do have fewer dining options at the Marriott I guess - 3 full service restaurants, two bars, and snacks available at the little shop (Starbucks, sandwiches, salads, pastries - not anything too great really!).
The refill mugs are outrageous priced - $35. Going for 4 weeks next time, I may buy one (or get one off Ebay since they're not chipped). They used to give one as a platinum gift, but stopped last year (grrr). I do like we can get POG in them!
Even though villas come with a spatula, I have a kind that I like better so bring a couple with me!
You could even make sandwiches or hotdogs in the room, use paper plates, and have a nice meal on the beach!
