As far as tourism in England goes, London gets the bulk of it.  When you think about it, London is the center of the civilized world.  This is where the British conquered most of the world from.  London is the cosmopolitan center of world culture for the modern era.  Istanbul and Rome are too far off the beaten track and they don't speak English.  The downside of London is that it's expensive.

The rest of England is a bunch of midsized towns and solitary tourist attractions scattered all over the country but there's so much history and so many attractions that you have to decide on exactly what you want and go directly for it otherwise you'll end up going to the usual tourist trap tourist attractions that have no real meaning like all the mausoleums of long-dead people from past history I saw when I went on a canned trip there.

Stonehenge in the Salisbury Plain about 95 miles southwest of London is about the biggest attraction outside of London followed by Windsor Castle about 20 miles west of London. 

England is big on literary heritage.  There are homages to great writers all over the place such as Chaucer, Rudyard Kipling, Jane Austen, Charles Dickens, Shakespeare, William Wordsworth, Samuel Taylor Coleridge, Jonathan Swift (Wales) and so on and so forth.

You have your two big college towns Oxford and Cambridge if you're into that kind of stuff.

If you're into castles and things like that, go to englishheritage.org.uk or nationaltrust.org.uk.

There are so many hotels, inns and guesthouses in England that wherever you go, you just have to look around to find one with vacancies.

British people go south to Brighton and north to the Lake District for vacation.

Europe is the number one tourist destination in the world.  People are interested in the historic charm of the Old World.  It will never go out of style.

The biggest mistakes people make when traveling is that they don't make up a plan beforehand and pack way too much stuff.  Pack light.  You're there for the experience. 

Don't travel with downer people who don't want to do the same things you do.  Onetime I went to England with some relatives and buddies who just wanted to see the nightlife.  I wanted to see Stonehenge, the war museum and a few other places so I ended up going alone.  They didn't even care about Stonehenge.  I learned my lesson.  If you're travelling to see a culture, don't travel with one-dimensional, mook hedonists.

Europe can be expensive if you take the usual touristy-hotel route or it can be cheap if you take the hostelling-backpacking way. 

One good thing about Europe is that it's so small compared to United States and Canada that travelling distances are short.  The train system is great.  You can get to almost anywhere by train except to Scandinavia where you need to go over water but there is now a bridge between Sweden and Denmark.
