I was successful in creating a new account. After dinking around I couldn't find my booking. After more attempts I found where you have to create that booking (booking #, ship, departure port, personal info) and then it pops up. So far so good. I haven't found where they show our past cruises and points accumulated thus far like the old site. Now that we are 4 Star, its not that big of a deal, but before it was fun to see where we were in climbing the status ladder...
Like most software upgrades, it's never easy.
Cheers!
