Ken's recommendations:

put heaters in the hotel, reduce the number of rooms, but make them cozier, more colorful and more comfortable, focus on bright new walls, restore or change all the furniture in the hotel, restoration is a good advice, since you don$$t need to spend a lot of money on furniture, better work on food, no more parties at the expense of the establishment, reduce the menu, replace the cook or train the same ones, monitor each serving of dishes and drinks yourself, communicate with hotel guests, clean the pool, make a jacuzzi area, and put a bar near the pool
