I stayed there about 30 years ago on a Corporate retreat. It was a dump then but they were in process of restoring it. Looks like they did a pretty good job!
Ah yes, My Faire Spouse and I spent a night there on our 2016 cross country trek. Quite an amazing place and they really did quite a remarkable overhaul. They made mini-suites out of clusters of three of the original rooms used when it was a health spa -- and it still works out to over 240 rooms! What is there now is a rebuild/enhancement after a fire in 1901 but its history as a health spa goes back to the mid 1800s. (My Visit)
