I suppose that would vary from person to person on what they’d consider “aspirational”.

To me personally I’d name these within the US -

Ventana Big Sur (obviously not changing categories, but you said Category aside)

Andaz Maui

Grand Hyatt Kauai

Alila Encinitas

Any of the Miraval properties but I know you can’t use the certificate there

I would say 99% of my stays are in Category 1-4 properties so I’m not too knowledgeable about properties out of that range which is another reason for the post.
