Same here, I'm so awake after 10... But my kids get up at 6-7 in the morning so I need to change my sleep schedule. Also, everything is designed for early risers, breakfast in hotel, from 6-9. But when I'm on vacation, I sleep till 9.

Same with work, getting to the office at 7 is fine, at 10 is frowned upon.

What helps is circadian lighting, I have homeassistant and it changes the color temperature of my ikea smart lights to yellow in the evening, and white during the day. The yellow lights prepare me for the sleep.
