well let's see? I can got to WDW for 7 days and spend no more than $4,500 for all 6 of us to lodge, enter the parks and eat all week inlcuding airfare.
for me to take the famil to Hawaii, It will cost us more than that for airfare alone! plus car rental since the is no free transportation from/to airport or around the island like you can do at WDW. meals are an added expense plus entertaiing ourselves each day since I'm not one who can just sit ona beach or hike every day. I want my kids to surf and hula lessons and see the sights.
I ahve been researching for a while and nothing is going to get us all there for less the $12,000 including most everything i can think of but not everything I'm sure.
Six of us, plus one extra, stayed at the Ka'anapali Alii, a very upscale condo located between the Westin and the Marriott for 9 days for a cost of $3200. We had full use of the in condo washer and dryer, free parking, full use of the cabana area complete with several gas grills and tables. Our car rental for that period did not exceed $320 (Ford Explorer). We stopped at Costco, had lunch at our favorite local places, (Lae Lani's, Aloha Plate Lunch, Maui Taco, etc, dinner out half of the time, Roy's, etc and we thoroughly enjoyed cooking out and having dinner in the dining area along the boardwalk. Most of the sights can be enjoyed on your own, the Hana Hwy, Oheo Gulch, IO needle, snorkeling from the beach. Surf lessons are readily available at a variety of prices. The Entertainment Book was worth the price alone for a sail to Molokini and snorkeling. On our Na Pali Coast sunset cruise, we enjoyed a 25% discount with our Entertainment coupon. Luaus can be deeply discounted if you look. The most expensive thing we ever did in Hawaii was the flight to Molokai and the mule ride down to the leper colony of Kaulapapa. It was also one of the best things we ever did.
On the Big Island of Hawaii, there are as many opportunities; the volcano, the Tsunami Museum, Akaka Falls, Waipio Valley, green sand beaches, hieus, kayaking on your own to Captain Cooks monoment, The Place of Refuge was affordable and interesting. I agree that airfare is expensive and if it weren't for our airmiles, via Delta's program and my American Express Delta Sky Miles card, six of us would have made it there only once.
I aggressively accumulate miles, using my card for everything and taking advantage of every double and triple mileage promotion available. DH and I have flown first class twice, (DSs in coach) for a total of four trips. We have enough miles to go again. One trip pays for another and miles accumulated at Disney go to Hawaii.
