Hi
We did week Waikiki beach, week aulani, week Disney Cali in 2016
In 2015 we did few days aulani plus Disney Hawaii cruise
If you fly in direct but with just stop over flights quite reasonable for where Hawaii is (depending when go)
We fly London to lax with BA. Stay overnight. Early flight next day to Honolulu with AA. All booked via BA
This was 11 hour flight then 6 hour do a long way. I like to get the worst flight out of the way then stay somewhere on way home (Disney Cali). For that far you need go for a nice break
London to Vancouver then on to Hawaii. Is reasonable
Skyscanner is very good as it allows you to put in details and they give you the best price
I loved aulani. It is beautiful but not a lot goes on at night. It's totally different to Disney parks and cruises where lots entertainment. We went for a week at aulani this time. There is not a great deal of food choices do a car would be handy but we did all the tours and sightseeing when at Waikiki as once at aulani your kids won't want to leave. There is ulu cafe which is like counter service. Character breakfast and dinner. AMA ama restaurant quite pricey
Across the road they have ABC which sells food. Pizza place. coffee shop. Mexican etc.
Look at the aulani website as well
Aulani is not in your face Disney as they had to keep it hawaiin but character photo meets. Kids club etc
If anything else please shout
