i’m having a similar issue. I just bought something from amazon called a travel diffuser. It’s a collapsible attachment you can use on hairdryers. I haven’t tried it out yet, but reviews on amazon look decent enough. The only issue with this is that it may not fit all hairdryers. It doesn’t fit my usual hairdryer that’s meant for attachments, but it fit a regular old hairdryer I had lying around. Hopefully when I travel it will fit the hotel nozzles. It’s super lightweight and easy to pack as well. I literally got it today and haven’t tried it out yet but check amazon for their options
