Most restaurants as well as casinos and the touristy places are conveniently located in the area of the low-rise and the high-rise hotel areas,very close to your hotel thus.
the Taxi fares range between $6 to $8 to any of these restaurants. To town shopping the fare ranges between $8 to $10 depending in which hotel you're staying.
Moving around in Taxis is safe and does'nt cost as much as if you were renting a car.
Renting a car might be a convenience but you're actually paying for something that most of the time you won't be using but still are paying for it even though most of the time it's parked in your hotel parking lot.
Put a scratch on it and they will take your car insurance fee.
Make a schedule of the places and restaurants that you would like to visit and you can figure out how much it's going to cost you, which is a lot less and with no risk att all.
Unfortunatelly one of the things we're not so happy to brag about is our "traffic", we have one of the worst if not the worst traffic in the carribbean with the most casualties.
So you will be a lot safer taking a Taxi and let a local who knows our traffic drive you around and besides it's a lot less expensive than renting a car. Be safe.
