These smart upgrades modernize Marriott rooms and deliver lasting returns. By cutting energy waste, reducing staff workload, and elevating the guest experience, this investment can pay for itself within a few years—potentially generating $3–5 million in added revenue and savings over time. And since Marriott already invests $1–2 billion annually in technology, this proposal is a worthwhile, scalable enhancement that clearly improves comfort and creates a more home-like, personalized stay for every guest.
