Where to go on vacation in the US as a European.

El

My husband and I planned a vacation to Cuba and Mexico for 6 weeks while I'm 20-26 weeks pregnant. My gynaecologist said I can go but I'm having second thoughts about it due to the Zika virus. We already booked our flights from Belgium - Cuba - Mexico - New York - Belgium. But we are considering just taking the flight from Belgium to Cuba and take a flight on the same day to the US to avoid Cuba and Mexico. And take our booked flight home from New York to Belgium 6 weeks later. But... where in the US should we go? We don't mind going different places and taking national flights. All sugestions are welcome!! Thanks!
