Travelling to St. Maarten for a week in March and other than a quick cruise ship stop it's our first visit. We've rented a car and i have a couple driving/traffic questions:

1. Will GPS (Google Maps) work on the island to help navigate around?
2. I keep hearing how bad traffic is particularly in the airport/simpson bay/maho area. If I'm staying in the Pelican Key area off Billy Folly road whats the best way or times to try to avoid a traffic mess?

Thanks in advance for the advice!
