The boss has decided she wants to go to Hawaii in the January holidays so we've booked 10 days on Oahu. Looks like theres enough to see, do and experience (our style of holiday) but we are weighing up taking a day trip (overnighter??) to another island if its worth it? Flights are cheap and quick.

Appears to be plenty of pro's and very few cons to all the islands but are there any standouts anyones been to? There will be us & her parents so ideally something that will keep us all happy.
