I can see why they would be real expensive. Let's do the math for example, 20 riders and a support team of 2. The support team obviously has to be paid, so let's say $150 a day per support team member. Then the cost of the support vehicle including gas and such. Let's call it $100 a day rental and $50 a day in gas. So right there, that's $450. Then THEIR hotel cost, which for two people, let's call it $100 a night. Then their meals. So right there, that's $4,000 a week minimum for support and I think I am lowballing it. Then of course a profit margin to run the company doing the supported tour. Then throw in your meals, your hotel rooms, etc....... Yea, very expensive.
