Probably you would have put an extra day to plan about this whole day. But the result associated with it is, happiness and savings in terms of money. Over all the trip would be a cheerful memorable one.
Let's assume you hadn't planned and you just start of the trip just like that, you would always have to travel with thoughts in mind whether you would get a nice place to stay, whether you would get it at normal prices or would you have to pay a premium, would you be able to visit all the places of interest, creating a lot of stir between family members.
