One of my least favorite thing that has to be done is getting the rental car for the trip. Because when you go to the airport you either have someone take you or you leave the car in long term parking. You have the luggage, and you have to fit everyone into the car, compared to if you have someone bringing you. Sometimes the kids are tired and not feeling the waiting part. Then I dislike when you have to pack the car up, your tired yourself from traveling and all you wanna do is just sit yourself.
