You can read the Hilton statement about the differences in the brands when they were talking about another brand that they are going to create here:
New Hilton Brands (Likely Coming in 2018)
Curio hotels are supposed to be 4-star independent hotels; Tapestry, 3-star independent/boutique hotels. Their appeal obviously is that they are smaller more boutique type properties. They are not like Tru. I have not been dissatisfied with the curio properties I have stayed at. Maybe you should read some of the threads for the Curio and Tapestry properties to see what they are about.
