The first time we did Aulani was in mid-November 2024. Place was so "awful" we just had to do it again in mid-Nov 2025.
Being from the Chicago area, the airfare to get there is significantly more than flying to Orlando. As to other costs, most things in Aulani and Oahu cost more than in Disney World and the Orlando area, particularly restaurant and alcohol costs which are much higher in Hawaii and Aulani, e.g., doing Ama Ama for three was $375 for just the meal before drinks, taxes, and tip; the luau that includes a meal with taxes was close to $700; and we did a nearby seafood restaurant for dinner and paid around $800 with taxes and tip.
However, you do avoid the cost for park tickets in Hawaii, and the prices for extras at the resort, such as Rainbow Reef snorkeling, are not too high. Rental car costs for the most recent trip were just a little more than our April trip to Disney World, and like other
DVC Resorts, DVC members have free parking at Aulani. Ultimately, outside of airfare costs, the total costs for three for our 8-day trip to Aulani was more than a like 8-day trip to Disney World (which includes park tickets).
Purely as a resort and its amenities, including character events, evening music, multiple pools -- and ignoring the Disney World parks -- I consider Aulani to be the best DVC Resort that exists. And weather is ideal, e.g., looked at the ten-day forecast for our last trip and everyday was predicted to be 80 as a high and 70 as a low, without high humidity, and that turned out to be an accurate prediction. I consider the trip to Aulani to have only two real downsides: (a) having to fly there and back has a high price, consumes huge amounts of time, and is like going through many hours of torture; and (b) driving from the airport to the resort is only about 25-miles but traffic can be bumper to bumper for quite a long time, e.g, our most recent 25-mile trip from the airport to Aulani took "only" an hour and 15 minutes.
