Staying there
A hotel room in The Netherlands emits about 14.8 kg CO₂e per night under UK Government 2026 factors — a country average per occupied room, not this or any particular hotel. 7 nights in one room adds roughly 104 kg — about 14.8× the carbon of one person getting there by rail from Brussels. Two sharing the room halve that share each; the journey does not halve.
