"I stayed at The Royal Park Hotel at Haneda Airport, and overall, it was a convenient but mixed experience.
The biggest advantage is the location. it’s directly in Terminal 3, which makes it incredibly easy, especially for early or late flights. You really can’t beat the convenience.
That said, the check-in process was mostly self-service using a machine, with very little human interaction. While it was efficient, I personally would have appreciated a bit more assistance or a warmer welcome.
The room itself was quite small. It worked for a short stay, but storage was minimal, just a small open space in the wall with hangers instead of a closet. There was also no iron in the room (though I’m sure one could be requested, we were just too tired to bother).
Another downside was the limited food options. Room service closed early at 9:30p and there weren’t many dining choices open in the airport at that hour, which made it a bit inconvenient.
Overall, while the hotel is very practical due to its location, the experience was just okay. I might stay here again purely for the convenience, but I would also consider other options."
