We had a butler last December, when we splurged and booked the Voyager Suite; while he was a nice guy, I wasn't overwhelmed with a desire to rush out and make sure I had another butler suite. He mentioned that he hadn't been a butler long, and he was rushed off his feet by a bunch of in suite parties that week (he didn't complain, but one night our dinner was brought by the head butler because ours had three parties to take care of). The afternoon snacks were nothing to get excited about (should we have ordered something specific? He never invited us to), and since we loved going for tea we could have done without those extra snacks.

When we had dinner in our suite, we didn't see the need for course-by-course service, and that probably frustrated him, but it also lightened his load.
