Do you plan your summer vacations or your just being spontaneous?

Once in a while we need a break from our busy life and spend some time with family and friends. To have a family bonding and to relax somewhere far from the city and pollution. Me and my family always plan our vacations ahead and have our hotel reservation and do our itineraries beforehand. It always saves our time and energy when we are on vacations and we don't have to worry about some things we might forget or a place where we will stay. We only have to enjoy ourselves and explore the place.
