Verdi the Traveler

Thanks for all the great advice!

Thank you all for the advice.  We booked a hotel downtown and will use your suggestions.

What I've read online is that it docks at Greenwich near the Cutty Sark.

We are flying into Heathrow from Chicago two days before embarking on the Viking "Into the Midnight Sun" cruise.  Any advice on where to stay and how to transport these long London distances?  We've never been to London before.
