Planning to make the pilgrimage a few days or weeks in advance will increase your anticipation and help you to think about what you hope to gain from your journey. Just as you would if you were physically going to make the journey, let friends and family know what you are going to do. Perhaps let them know when you will not be available to be contacted. Its always good to put your phone on aeroplane mode or even turn it off if its not the device  you are using to make the journey on. Make sure you set aside time in your diary for your travelling just as you would if you were going to leave your house. If you have opportunity to read books , or look at online information about the area we will be travelling to virtually , this too will help.
Perhaps you could also think of what you will leave behind on the day or days when you are making the journey. Something you would be forced to leave if you were making the physical pilgrimage. This again will tune your senses to the adventure. 
Most of all, be willing to bring yourself, however you are feeling and whatever your hopes or fears.
