Review our startup - EventGel
uptown: I'd recommend placing some focus on what it looks like when printed.  The nature of many events is that people will be going somewhere they may not be familiar with.  If you look at how things are printed out, you'll see that it spans multiple pages, and isn't very easily readable.  The printable version probably only needs a subset of what you show on the on-screen view, but you should lay it out in a manner so it can all fit on one piece of paper.
