I will go to Hawaii this next May.
I'll spend around 12 days and 3-4 of them in Honolulu.
I'd like to know what should I visit for sure and how should I travel If I wanna go from one island to another? I'd like to know the cheapest ways to travel from island to island.
Also, I would like to know what are the main thing I should visit, like wonderful landscapes or something like that.
The last thing is that I would like to do some dives if somebody could help out with some good locations to do it, would be awesome!
