My Hawaii experience is very similar. I paid about $750/RT air, $150/night for a beautiful townhouse condo on the Kings golf course at Waikaloa Villiage on the big island. The rental car was very inexpensive for a week. We explored the island, visiting many inexpensive or free attractions, stocked up at Costco and ate some meals at the home, and found some great local restaurants. It was less than a 10 day Disney trip for sure.
Yup. Us too. I managed to get FF tickets for our Oahu vacation this summer, but if I hadn't, I would have spent about $900 for two of us (that's total, not each) booking early and using the Alaska Credit Card Companion voucher (one of the few true travel deals that still seems to exist!) That is traveling from the West Coast, so it is cheaper than coming from the East Coast, but it basically matches or is better than what we would pay to fly to FL.
Our beach-front (feet from the water) one bedroom condo on the North Shore is $2600 for 11 nights (incl. all cleaning fees, etc) so about $235 per night. That includes a full kitchen and the use of lots of miscellaneous items like beach chairs, a beach umbrella, snorkel equipment, etc. Even with the high price of groceries in Hawaii, our food costs are cheaper than a Disney vacation because we eat many meals in. We eat out here and there - and enjoy MUCH better quality food than we could get at Disney - but honestly, eating out gets old after a couple of days and I prefer to cook, even on vacation. Of course, I have DD16 to clean LOL
Rental cars on Oahu are generally cheap, although this year so far the rates are a bit higher than they have in the past - but last time we went, the prices dropped 8-10 weeks out, I hope that will be the case again.
Activities are cheap for us in Hawaii - there are so many things to do that are inexpensive or flat out free! Pearl Harbor, all sorts of hikes, snorkeling at different sites (all beaches in Hawaii are public), museums, even surfing lessons for DD (hello Groupon!) I only have $200 budgeted for activities for 2 of us over our entire 12 days and I think that's probably more than I need!
All in, I spend about $300 more for 11 nights in Hawaii as I spend for a stay at a value for the same amount of time at Disney. But that extra bit gets us better food, a wider variety of experiences, and a nicer place to stay. And the biggest difference? I actually feel relaxed after a Hawaiian vacation. Whereas I come home from Disney more exhausted than when I left from all the go-go-go to try and get the most value out of it!
Of course, all that said, DD still prefers Disney to Hawaii. She's not a beach gal. But since I pay the bills, I get to pick and this year it's Hawaii
