To da boards Bob...I hope your tag tells me what kinda guy you are!!!
I did a 10 day Europe trip in Sept, and these are the cities I covered in that time...
Amsterdam, Netherlands 2 days
Nijmegen, Netherlands 1 1/2 days
Antwerp, Belgium 1/2 day
Bruges, Belgium 1/2 day
Edinburgh, Scotland 2 1/2 days
Glasgow Scotland 1 1/2 days
Belfast, Northern Ireland 2 days
I enjoyed every minute of my trip, and have no regrets about how much time I had to travel..I worked with what I had and saw what I could in the time I had...I think I did pretty good...
So to answer your question, yes, it is worth the money, I would do it again in a second if I could.
