With no promise to be able to attend myself, those who cannot make it to Europe or upstate New York may find it easier to get to Milwaukee. I know that sounds like an odd location, but Tolkien's papers are there, at Marquette University. I can't make any promises about how fun it would be, since I haven't been there since high school (many, many, many years ago.) There's always Lake Michegan and Wisconsin beer and brats, not to mention a Jesuit University Library/Archive to explore. Librarians can be very gracious, and it would be nice to see some of Tolkien's work in his own handwriting.
By the way, here's what Marquette is currently showing on their website about their Tolkien Archive:

Actually seems a little out of date to me, though the books available look interesting.
Anyway, it's just a suggestion.
