Europe!

Alrighty friends and readers, I need your help!

My favorite boys (and some of Jeremy's family) are heading to Europe in about 8 days! 

While we're there, we'll have three days in Brussels, three days near Bruges and then we're also making one-day trips to Paris and London.

What's your advice for these cities?

After doing some research, I've come up with a few ideas:

For London, I'm thinking of doing the Original Bus Tour. That will provide us with 24 hours of transportation, on-and-off bus stops that go by every stop you can think of (other than Abbey Road), three different bus tours, three different walking tours AND a river tour! Also, Jacob's admission is free. 

As far as Paris, we have found several "one day in Paris" web sites which provide great advice.

So... who has traveled to London, Paris, Brussels and/or Bruges? What's your best advice?
