Aircon in hotel room leaking water throughout the night

Spent the night at one of my favourite hotels in summer - City Lodge Hatfield. It got so hot at night that I switched on the air conditioner. After about two hours when I switched it off, I realised that it (AC) was leaking water. I put one of the bins under it to capture the water but really- hearing this thing drip the whole night was frustrating. I couldn’t fall asleep
