The Glasgow Marriott has cracked the code on making room service profitable again, and the answer is mobile ordering. By deploying IRIS Mobile Ordering and Digital Guest Directory, the hotel pulled off a 24% revenue increase and a 23% jump in order volume. Even better, 80% of all room service orders now come through the digital channel.

That’s not just a tech upgrade: it’s a playbook for any hotel that still treats room service as an afterthought. The IRIS platform lets guests browse menus, order and pay from their phones, no waiting for a paper menu or a busy phone line. Read the full case study on HospitalityNet.

My take? This is the kind of low‑hanging fruit too many hotels leave on the tree. Room service has been dying a slow death because the experience is clunky. A mobile order‑and‑pay flow fixes that instantly. The Marriott team didn’t invent anything radical: they just removed friction. And the numbers prove it works. If you run a hotel and your room service is still paper‑based, you’re leaving 24% on the table.
