การส่งข้อความระหว่างเข้าพัก

In-stay messaging covers conversations between check-in and checkout: housekeeping requests, late-checkout asks, restaurant recommendations, issue resolution. Two-way SMS and WhatsApp dominate this layer because in-stay guests rarely open the hotel app or email. AI concierge platforms layer on top of the in-stay channel to deflect repetitive questions before they reach the front desk.
