<human>: Can you provide a brief overview of the text?

So last week I went on a week long cruise with my family and another family that my parents have known for a while. They have a daughter of the same age, I'll call her Macy. 

Macy and her family live 2 1/2 hours away by plane so we don't see each other much, but just the right amount. 

So as the week started, Macy and I got caught up a bit and talked for a while. A few days into the cruise I started to have some thoughts and feelings about Macy, but didn't know that they would develop any further than that. Near the end of the week I knew for sure that I had strong feelings for her and once the cruise was over I was in a state of not knowing what to do. 

We have started communicating daily since then and it's just small talk and whatever's on our minds. 

I want to let her know how I feel about her but I'm not sure if it's the right move. I mean sure she lives a decent time away from me so what does it matter? Well we are still great friends and I don't want to ruin the friendship by such a silly thing.
<bot>: Went on a vacation with a family friend who lives far away and, developed feelings for her. Not sure if it would be smart or not to tell her how I feel about her.
