Used butler service at SR Monarch Beach as well
I also had a recent experience with the butler at SR Monarch Beach. Was in an Executive Suite and mornings included French Press coffee service with biscotti and newspaper.
All I had to do was pick up the phone, press the butler button, and request the coffee service. Arrived within 5 minutes or so and was complimentary (except for the tip).
At this hotel, the butler service is only available for suites. I'm sure there are certain exceptions though if the price or loyalty is right.
