First of all, they had messed up our booked for 2 king rooms so son gets upgraded - fine.
Then get to my room - very dark so don’t see outside. All night kept awake by loud humming, beeping and whirring. Too tired to go back to reception.
Turns out I was inside from all the ventilation shafts etc. Noisy from people going past at all times of the night.
Worst night sleep ever in a hotel.
Do not accept room 606.
