Hotel breakfasts are shit anyway. They are designed for salesmen up at 630 to eat then chase the Glengarry leads.

I've seen variability, but 9:00am seems a bit earlier than usual. I feel like 10:00 is the standard, unless it's a corporate hotel focused on business clients. Or maybe I'm staying at places that expect me to stay out late.

Same person probably invented "Continental breakfast"

Just go out into the city and find a nice café for breakfast. It's often better than the standard hotel menu.

They want you to be up and ready so you leave

We set an alarm to go get breakfast ASAP when it starts and then would come back and sleep another couple hours. Worked every time.

A severe case of "wrong hotel". There are hotels for holidays, and hotels for business travellers. If they offer breakfast from 6 to 9, they are obviously in the "business travellers" category.

On the other hand, if your idea of a holiday is sleeping half the day, why bother leaving home?

Ah such a sweet summer child. The vast majority of hotels aren't for people on vacation. They are for business travelers. That is where the money is. Catering to vacation travelers is like McDonald's serving breakfast, or a bagel shop selling dinner.
