'Don't have to' is permissive. It means doing something is not an obligation. I don't have to work tomorrow so we can go to the country. John has a car now so he doesn't have to take the train every day.
It doesn't tell you whether the action is actually done: Mary doesn't have to phone her mother every day - but she always does! Employees don't have to start at eight in the morning so I always go in at nine and stay later.
Notice the infinitive here: It's nice having a dishwasher and not to have to do the washing up. And a gerund: The kids go swimming every day. They like not having to wash! These are interchangeable. You can also say: It's nice having a dishwasher and not having to do the washing up. The kids go swimming every day. They like not to have to wash! Both are OK.
At least we _____ get up so early during the holidays.
