She did not get her money's worth. From our observation, it is not unsafe for a woman to travel alone in Turkey. The bodyguards were unnecessary. She could have booked a flight from Istanbul to Kayseri for $60, a bus from Kayseri to Cappadocia for $14, a night at a hotel in Goreme for $100 or less, a performance by the whirling dervishes for $40. In other words, she could have spent less than $500, or paid for a friend to accompany her from the states, for less than what she paid.
If at all possible, Turkey should be savored, not crammed into a few days. If you can't spend at the very least a week in this country, don't bother coming until you can spend the time...unless of course you're here on business and your boss is paying the tab.
