Nail questions

I’m going on a weeklong tropical vacation. I’ve gotten pedis before but not really many manis.

I have a few questions:

1) how long does a mani last if I get regular polish? I’m not going to do fake nails or gel polish. So I’m wondering if regular polish would even last a week on my nails?

2) I want to get a bright (maybe pink-ish) color on my toes. But for my fingers, I want something quite subtle. Would it be weird to have a different color on my fingers?

3) any suggestions for a finger nail color that would look good on my skin tone and that would go well with a bright toe color?
