Thanks for the advice here, we just came back from amazing our first ever Europe trip. Covered a lot of places (London, Brussels, Paris, Zurich, Pisa, Florence, Rome, Santorini, Mykonos and Athens), in almost 3 weeks. Little tired now from all the traveling, but coming out of jet-lag slowly. We traveled in economy class, so my trip report is not something you guys will be interested in

But, just wanted to say lots of thanks to everyone for the very helpful advice. Couldn't have done this without all of your help. Thanks everyone. God Bless you, and lets keep this brotherhood going, helping everyone.
