6 month old in a pool?

Deedee
We will be going on vacation in May (to Wisconsin Dells) and my baby will be a week away from being 6 months, I called to make an appointment and asked them if she needed a pre check up and they said no she won't, but I did have questions for the doctor. 
1) can my baby go in the water? Not in but with me. Will it affect her big time? Should I just avoid it?
2) Is there a mosquito repellent that anyone recommends specifically for a baby? 
And any advice?
