€90?? More like €50, and this gets you a flexible ticket so you can take any train
1st class can be as low as €64.
The OP probably doesn't want to go to AMS (the airport) but more likely somewhere in the city and will likely need to get some form of transportation from AMS anyway, so why not just arrive by train?
