NO NO NO, a DW is perfect for you if its what you had always wanted. Dont get frustrated, or do because even the most laid back of us DW girls have ended up getting a little frustrated over some part of the DW experience. Slthough DW are usually a lot less stressfull than planning a humongo at home wedding there are still stresses. Just take a deep breath and think of a way to get through it. There will be family members complaining about something no matter where you have your wedding.
As far as the hurricane scare goes, maybe look into some areas that arent prone to hurricanes, or and, make sure you dont plan durring hurricane season. If you do this maybe your FI will be more at ease.
Hope that helped a little
