If you’re booked into the Hilton, you may want to consider the Executive Rooms, they can often be available as a cash upgrade or Hilton Status. These rooms are in a building that’s a bit of a distance from reception (internal) but it’s a more modern building and I find it quieter. There is a Exec Lounge (or was) that might be better for the morning, you can luggage n bits in the room before leaving, having been fed and watered.

Others might be able to confirm the lounge or hotel status as I personally haven’t visited since pre-Covid. Hence the was rather than is. overall a good hotel for being at the airport, pre-flight.
