Guest services in a hotel generally include tasks that directly relate to the comfort and needs of the guest within the hotel premises.
- Handling guest luggage is a common part of guest services, typically performed by bellboys.
- Delivering newspapers in accommodations is also a standard service offered to guests, especially in upscale hotels.
- Conducting room cleaning is a primary responsibility of the housekeeping staff, ensuring rooms are cleaned and maintained.
However, arranging for reservations at places outside the hotel falls outside the scope of hotel guest services and is usually handled by external services or travel agents.
Thus, the correct answer is Arranging for reservations at places outside the hotel.
