I actually love to plan trips... just not go on them!

Could you plan for things you want to do or places you want to see and focus on them? Is there anything you could reward yourself with on the trip, like a massage (not my favorite, but many like them) or the fact that you don't have to do any work/cooking/whichever chore you will enjoy getting out of (for me, it would be cleaning the litter box...)?
I would also get myself a couple of books or magazines I really look forward to reading at night, or maybe a couple of music CDs to play in the car or over headphones. Music helps me enormously in the car when I feel uncomfortable driving - especially singing out loud, because that forces you to breathe properly and releases emotion.
