Bachelorette Party Nightmare! About to cry

My MOH and BM's planned my bachelorette weekend on 10/14-10/16 and won't tell me where we are going. I am super excited!!! We live in Orlando FL so I'm assuming we are going to Jacksonville or Miami. Well in Miami there is the Zika Virus going around and FH started freaking out about it. Saying that he doesn't want us to go to Miami. Well after I brought this to the attention to my bridesmaids of him freaking out, my bridesmaids decided to tell me what we are doing. They told me that we are going to Miami and they have already planned and booked the entire weekend. Spent hundreds of dollars and is not refundable. I want to be super excited but I can't help but stress about everything now. Does anyone have any advice or are knowledgeable on this Zika Virus? I heard that it's carried in mosquitoes and that it only really affects pregnant woman. I am not pregant and we are not trying until after we are married. I think that FH is making it into a bigger issue than it is needs to be....
