Even though the new website says Azamara Upgrade bidding tool is currently unavailable due to the transition to new systems, last night I got an email from Azamara saying I'm eligible for a stateroom upgrade (sailing Apr 29). The email links to the bidding site seem to work nicely. However, I cannot say if it's a new bidding site or not, since this is my first cruise with Azamara, so I've got nothing to compare to. There is a currency problem, since the email and web page show all offers in NOK though I've done my reservation in EUR and before the webpage maintenance break my account showed OBC in EUR too.
