In principle, working for a hotel is permissible as long as one stays away from what is unlawful. As for alcohol, there are ten categories of people who are cursed due to being involved with it. Touching alcohol containers is not one of those categories. The Prophet (peace and blessings be upon him) cursed ten categories of people: “Truly, Allah has cursed khamr and has cursed the one who produces it, the one for whom it is produced, the one who drinks it, the one who serves it, the one who carries it, the one for whom it is carried, the one who sells it, the one who earns from the sale of it, the one who buys it, and the one for whom it is bought” (At-Tirmidhi and Ibn Majah).

Dr. Monzer Kahf, a scholar in Islamic economics and a financial expert, states the following: The Prophet (peace and blessings be upon him) informed us that there are ten functions that Allah prohibited in regard to alcohol; serving it is one of these ten functions, while touching its bottle is not one of them.
therefore, if while passing between shelves one touches boxes or bottles of alcohol, one does not break any prohibition. But carrying it (mentioned by the Prophet) and serving it (is also mentioned by the Prophet) to a person, in a restaurant or in a hotel room, are prohibited and you need to avoid these actions too.
