Ingredients 

A full bucket of happiness 
A happy family 
A long list of ideas
Being grateful
Directions 

In order to have the best vacation you need to have a bunch of time on your hands. You will make the most memorable memories when you are happy and with your family. 
Having ideas will get you places. Being grateful for what you have is the best thing you can ask for. Taking the time you have to write down those ideas are probably the best things you can do for your family. 
You will then have to figure out what you want to do as a family to make the memories you want from the list you made. 
Remembering the little things means the most.
