Paul,
Have a great, safe cruise. I'll be eagerly awaiting your reports. The Epic looks to be a great and innovative ship and I'll love to hear about some of those innovations. Such as the Blue Man group, Second City and other entertainment.
I am also interested in the cabin configurations in the balcony cabins. Initial reports aren't too good and there is more to the configuration than just having the sink in the cabin.
Take care,
Mike
