I don't think that anything you do for 2 weeks is going to make much difference, in terms of training. I'd say ride as much as you feel like this week (not none), and don't ride very much if at all for the 2 days before you leave, so you don't start tired. Try to get some sleep, eat normally, and relax! It's going to be FUN!
I know you guys had some issues - I hope you have managed to talk about what was bothering you and come up with some solutions. Sometimes for me, just telling the other person that I'm grumpy or tired or hungry can make all the difference. Also, you might want to plan for a little just-getting-into-camp snack (with beer, in my case!) so you can relax during the setting-up-the-tent and making-dinner part of the day, so you aren't hurrying b/c you are starving. Learning to do that made my camping experiences sooo much better.
hope you guys have a fantastic trip!
