I have to admit that I was a bit underwhelmed by the new showerheads. At least you can now be assured of not getting any crummy showerheads in HI Expresses. I do like the curved bars when the hotel has them. I don't believe they are part of the company-wide shower revamp.
For their next big idea, maybe they can get the same alarm clock in every room in all locations. It would be nice not to have to always figure out how to set the alarm when you arrive at a new location.
