The OP goes on to genuinely talk about the advantage of being able to leave when they desire (usually only attending day 1), and the observation that their leaving early was worthwhile, as they were first in line to access the car parking area —- so it would seem very much to not be /s.

Being flexible with DB is expensive. Getting somewhere at all is generally cheap. Getting somewhere at a reasonable time is usually ok~ish priced. But being able to just take any train? €€€

https://belgiantrain.be for finding trains and tickets to/from the nearest station, Etterbeek (or use another station if you want to take the tram, where you just swipe a bank card). The ticket is valid for any train going to your destination. For those <26yo, the price is discounted. Welkenraedt is an intercity station with free parking that goes directly to Brussels, in case that happens to be near to someone reading this
Same with the Netherlands. Sadly no intercity stations have free parking but Nuth is on the path north and the highway exit basically ends in its parking lot. After a few stops you can switch to an intercity to Amsterdam
