Mystery Postcard

Sinced my last 2 puzzles were solved within 2 posts I thought I’d up the ante a little. Try this one.
Hello Dopers,

I’ve visited unbelievable castles, lodges, zoos, every kind of museum.

So, where am I?

Disney World?

Nope, it’s a real country.

germany

It can’t be Germany, he didn’t mention Sultyr Goddesses.

Um, Scotland?

California?

London?

Oh country. England.

Nope, I’ll give you a hint, the fact I saw castles, lodges, zoos and museums doesn’t mean anything except I chose to say that I saw those rather than, say, Yellowstone park or The Alamo.

BTW, the country is not America.

it’s got to be Switzerland but Belgium is good for most of the things you saw - especially ALL kinds of museums

ohh… Disneyland then?

Well, no, but not Canada either.

I got it!

Antartica.

'Fraid not.

Oops, I’ve made an error in the postcard’s layout, It should read thusly.

I’ve changed visited to seen in this Card. The puzzle will work perfectly now, it did work before but it makes more sense like this.

My apologies for the Error.

Well that changes everything, dammit!

Hmmmm. The Vatican?

Scratch my previous feeble attempts.

I’m thinking the answer is something like a bookstore, cardshop, or a library. Something stupid and irritating like that.

Are you taking questions?

Nope, Chris, I’m not in a bookshop. Keep trying.
Hints: Why do you think such a small alteration (changing Visited to Seen) would make a difference? Don’t try to analyse the content, look at how it’s written.

Ok, one more bump and I’ll tell you the answer.

Austria?

You’ve used every letter of the alphabet except A, R, W and Y.

Yemen?
