I am currently on broadband, but I spent a long time on dial up. I can see that the new website would be a "dog" on a slow connection. My suggestion would be to have a relatively simple (but effective) page load initially with an option available for a slow internet connection for the other pages and content.
I (along with others apparently) have had issues with getting the videos to play. I also noticed the typos, etc. Hopefully those will be corrected promptly.
Now we'll just have to see if the site does its job and sells tickets.
