Overplanning isn't bad! I wish I could do that but with our careers that far isn't possible, even this is going to be a bit odd but I know its slow enough we won't have issues to take it off.
I wish I could do vacations over Thanksgiving or Christmas, but my husband is in retail management & we live in a very seasonal town now, so vacations from middle of October to end of January are just a no-go. I work in engineering for a manufacturing environment & know I have to avoid the very last week of the month from now on for vacations, luckily, we tend to shy away from that week of the month. Also, without children, I don't have to worry about taking off the highly requested times off work as we tend to go places when school is in session.
Thats a great reason to book this early!
