opinions and advice please

My plan for pictures is to go to North Port Harbor and take pictures by the water, dock.
However, IDK what to do if it rains
I really dont want to spend the money to book the Vanderbuilt or Westbury Gardens because I dont see spending hundreds of dollars for a backup plan
My ceremony starts at 615 and our ketubah signing is 545..I can not get to larkfield to take pictures till 5. Therefore,
Im looking for advice on where to take pictures before 5 since 45 minutes will not be enough..looking for a place in North Port/Brentwood/Commack or very close by!

Thanks so much :)
