The tours are fast paced.
The rooms are spartan (but clean, and comfortable)
No bellhops, you must carry your own luggage.
Your dinners are at restaraunts that "common" people would eat at, not
where tourists eat. (One teacher actually said "why aren't I eating
French food", when we were in Paris...relating French food to what her
restaurants in her town cooked)
You will encounter other groups, and in my case I only take 8 kids, so
we are always mixed in with other groups, and you do not have control
over them, or even have the "right" to control them.
The upside is: you will see more than you can imagine, have a wonderful
time bonding with everyone including your tour director (who, I might
add, is really a delight, intellligent, witty, and resourceful), and if
you prioritize your spare time, you can shop till you drop.)
This year I am going on two trips!!!
