Mandalay Bay, Las Vegas
"I'd like to arrange coffee delivery tomorrow morning, please."
"We can offer 5:30a - 6:00a. There are no other options at this time but you can call in the morning if you like."
Next morning:
"I'd like to order room service of coffee and a pumpernickel muffin."
"It will be 70 minutes for delivery."
Lesson learned:
During trade show season, confirm room service delivery for the duration of stay at time of check-in.
