For those that are visiting Central Park you should determine if you want a tour guide or not. There are tons of different ways to see Central Park and a tour guide is a great way to make sure that you are seeing everything and that you are going to be able to go to where you want to go. For those that are not interested in being able to see the whole park in one go or that are more concerned with just wandering around, you may not benefit from a guide. If you have a larger group, you have children, or you have people that are not really concerned with being left on their own to explore, a guide is going to be a wonderful thing to have.
