Thank you for the response. Since Floriade is only once every ten years, we figured this was our chance, at least for a long time. It seems that very few folks have heard of it, though, and that makes us question whether it would be worth it to go out of our way for it. We are still planning the post-London part of the trip, and are now feeling that we would go to Floriade if we were in the general area, but would probably not go out of the way for it. Thanks again.
