Sorry your first tour didn't turn out the way you hoped but I bet it's still something you would do again in a heartbeat.
My first weekend tour with a group went as planned, except I tried to trim weight by skimping on sleep gear. I learned something from that! The next one was by myself with my dog. We were on a road with no services whatsoever and I ran out of food and was on the verge of running out of water because I dumped the last of the water from my dromedary bag so I could lighten my load up a giant hill. Lesson learned again! I had to call for a ride home.

But I went on my next tour in the Southern Utah desert with a handful of other people and had the time of my life...learned a lot from that trip as well though no major mistakes on my part in this one.
I hope you continue to tour...you'll have a great time despite the problems.
