Stacey Roberts, 26, was staying in the hotel with her six-month-old son and partner when they were jolted awake by by the fire alarm.
She said: "We're homeless and that's where Flintshire County Council placed us. We booked in on Saturday night, so now we're sitting with friends and family until the council office opens.
"The Gateway To Wales was our home. It's just awful."
The hotel, understood to have around 40 rooms, appears to have been burnt to a shell, according to one witness.
Danny Lawton, who lives in new flats next to the hotel with his girlfriend and baby, said he was woken up by police banging on his door just before 5am.
The 24-year-old machine operator said: "We grabbed the baby and her stuff and headed downstairs, and the car park was already full of people. The heat coming off the fire was immense.
"The whole roof and top floor was on fire and the surrounding area was just full of smoke and flashing blue lights. There was a dozen or more fire trucks and police cars.
"I was told to move my car as quick as I could as the heat would melt it - that's how close it was.
"As far as I'm aware the fire has been put out and the building has burnt down to just a shell."
People with nowhere to go were offered shelter in the fire station, Mr Lawton added.
More than a dozen emergency services vehicles including seven fire engines and four ambulances raced to the scene after the alarm was raised at around 4.30am.
North Wales Fire and Rescue said in a statement: "Firefighters are currently in attendance at a fire at a hotel on Welsh Road in Deeside.
