Notes and cautionary points

• Brand vs property: large chains (Marriott, Hilton, etc.) often have tiered Wi‑Fi policies—loyalty members and direct bookings usually get complimentary enhanced or premium speeds, while third‑party bookings sometimes do not. Check the property terms and your loyalty status before booking. (marriott.com)
• Variable experiences: even top hotels occasionally have user reports of slower speeds during peak evening hours or at specific events — if absolute speed is critical, ask the hotel for measured/guaranteed bandwidth for your room or meeting space. (Some hotels can reserve dedicated bandwidth for meetings at an extra charge.) (thenationalnews.com)

• Ask for a wired Ethernet port or a room on a lower‑congestion floor, or book executive/club access — some hotels provide better bandwidth in executive lounges or club floors. (For events, request a dedicated circuit or guaranteed bandwidth.) (marriott.com)
• Test on arrival: run a quick speed test and ask the front desk/IT to escalate if speeds are below what you need. Many hotels will
