You're not asking for too much. You just want your hair put away, the scalp still accessible and your edges at peace. A few flat twists can give you all three without an extension appointment or an hour-long styling session.
Fresh braids and twist extensions are supposed to be cute. They are not supposed to make us spend the first three days wondering if we've made a terrible mistake... if our scalp is in danger, under duress, if you need to get the very expensive, and time-consuming situation removed immediately. I don't wish that type of anxiety on anyone.
