Can I hide in the hotel?

It shouldn't be possible. It is best to draw curtains in the bedroom to prevent light from passing through.

The method of hiding stars is as follows: the time of hiding stars is from the 15th day of the first month, from the night of 17 to the night of 19. Light eight candles, block the window room, sit quietly facing west, light three incense sticks, put them in front of the table, use the lucky star symbol (which can also be used as a blessing pendant of a bronze stove or a personal pendant), and press the symbol with an axe. Sit still and you can eat something or read a book.
