What were your thoughts on it? Would you do it if you could? Do you think it's worth it? I really don't think there's much of a difference in price; esp. with today's prices and today's problems. Time is valuable, though it would be nice if I were traveling with 3-4 other people as costs would be absorbed more easily.
I've been on a few (for personal use, though personal trips tend to turn into business trips) and can't find any fault.
