Unfortunatly DLRP don't seem to publish this information. It must be held as they must monitor it in-house. I think it's possibly to do with the fact that they aren't making a major profit yet. I'd expect that information to become more commen knowledge as the profits for the resort increase.
Experience shows that the weekends are the busiest time of the week, Saturday's and Sunday morning's being the busiest of the weekend.
I know for sure that the Santa Fe and Cheyenne Hotels are all sold out this Saturday Night and the following Saturday night... but they are practically empty on the Sunday night!
