Hi - We are interested in doing the new 2008 Germany trip with ABD. I've been searching for this info and I can't seem to find it. Someone said that booking one of these trips via phone can take 45 minutes, so I'd like to have as much information myself before I call. How much is the deposit that is needed at booking? If ABD books airfare at that time, is the airfare due at booking? How far in advance of your trip is the balance due? Thanks!
