I need the perfect hairstyle for my cruise?

[MizVictoria]

Im going on a 7 day cruise and I want a hairstyle that wont be too much for me to handle. I was thinking a sew in, braids, or micro fusion extensions. Here is a list of choices that I'd prefer:

Sew-in: virgin Brazilian bohemian
virgin Brazilian body wave
**(might make these into wigs)**

Braids: micros
long box braids

Micro fusion: straight hair

I love love love having a full head of hair and looking fabulous. But its going to be moist out and I want something easy. I love doing hair so I don't mind if I get a sew-in. But they do have 2 formal nights for dinner and I want to look good. I've had all of them before so I don't know which to choose.
