If you have never traveled before and you suddenly arrive in a new country, the culture shock that you are going to end up experiencing will be quite intense. You would not know the language and you would be completely unfamiliar with the culture and customs of the country that you are currently in, which is why you might feel a little uncertain about travelling in the first place.
Luckily, there are things that you can do when you arrive in a new country in order to make your stay just a little more pleasant. To start off with, you can hire an airport shuttle to get you out of the airport. Taxi drivers in a lot of new countries tend to be untrustworthy. They would charge you too much for the trip thinking that you are a rich foreigner who can afford it, and if you are not careful you might even become the victim of a crime since a lot of these taxi drivers are looking for people to rob. Even if you end up with a taxi driver of good moral fiber, chances are that you would not be able to get a very good experience with him because he would probably not know enough to take you to any nice places.
Instead of going through all of that hassle, you can just go for something a little more reliable like an airport shuttle. These shuttle services are driven by people that are extremely safe to be around and they know a lot about the city you are in which would allow them to provide you with some very useful information about what hotels you can go to and which places are actually worth visiting for an exciting time.
