From the FAQ:
Q: What out of pocket expenses can I expect?
A: If you register as a Fully-Guided “all-inclusive” tour, then you’ll only pay for your lunches, gas, tolls, incidentals at the hotels, alcoholic beverages, dinners on the rest days and entry into National Parks. If you register as a Self-Guided rider, then you’ll be paying all your own expenses: all meals, hotels, incidentals, alcoholic beverages, fuel, National Park entry fees, breakdown assistance, towing, etc. Either way you register you’ll pay for your own bike maintenance and repairs (and of course your speeding tickets. 🙂 )
