Many friends don't know how to take the shuttle bus. I have the same doubts, so I would like to comment on this and hope it can help everyone~
After you arrive at the airport, look for the sign: Hotel Shuttle Bus. If you can't find it, look near Burger King and you will soon arrive outside. Outside, you will find that many hotels are picking up people. Be sure to check which bus this hotel takes. To go to the city center, you can take the airport bus to the airport first, and then buy a train ticket to Amsterdam's central train station. It is quite convenient~ (mainly because Amsterdam's city center hotels are small and expensive)
At the same time, I don't think it is necessary to buy breakfast. It is relatively average. You can go to the McDonald's next door. (Breakfast is 17.75€ per person, which is indeed a little expensive)
