Overnight at Schiphol airport or hotel needed? [duplicate]

I will go from Belgium (Brussels Midi Railway Station) to Netherlands (Schiphol airport) so I am supposed to arrive there on Saturday at 11:24pm and then wait like 10h for my next flight which takes place on Sunday at 12:30pm but I am not allowed to do the check-in until 9:30am.

So, I'd like to know if I would need to book a hotel or (if not) how "rude" is to sleep at Schiphol airport. For sure this is different from airport to airport and I was thinking to probably follow this but I am not sure.

However, if booking a hotel is needed, I thought about getting a room at Mercure (inside the airport) but I am not sure if I will be allowed to get inside since I won't be in transit/boarding area until 9:30am - Is that possible?

On the other hand, if that's not the right hotel, which one could fit better from the following list of hotels available at Schiphol for this scenario?
