Here’s a map of the sixteen counties covering central Florida.
Counties: Polk, Osceola, Brevard, Orange, Seminole and Lake tend to be associated with the Orlando region and knowing where the county you are visiting or based will help with county and community services in particular with weather and traffic alerts via TV, radio and internet.
Maps: Different areas in Orlando have different maps so be sure to look out for them when you arrive in a new town. See here http://media.visitorlando.com/contacts-and-media-requests/orlando-map-link/ where you can download your own town map and help get your bearings.
Alternatively, most areas in Orlando will have a tourist help point where you can purchase a town map. If staying in a hotel, be sure to ask at the front desk for city and town maps of Orlando.
GPS: These come very handy, especially when you’re driving around in an unfamiliar place! Most car rentals offer GPS services as an optional extra in the car and will charge approximately $15-20 a day. Depending on the length of your stay, it can be more cost effective to purchase a GPS at the local supermarkets such as Walmart for around $90 which may work out overall cheaper than a rental cost; this way, you also have your own GPS handy for future holidays.
