Forget all the naysayers. You'll learn how to manage your rest and have an amazing time. And if you don't you can always bid off it and at least say you tried. I've been on the 330 for nearly 2 years and have loved every minute of it. Even the occasional long bus ride is no big deal...just close your eyes for a little power nap. And first break going over isn't that big of a deal to me either. You'll figure out what works for you and adjust. I can tell by your enthusiasm that you are going to have a blast. There is a reason it's so senior.
