Getting into Syd Norman's early is no longer a perk in the Haven. I asked about it on the Escape New Year cruise and was told by the concierge that they had received a memo from HQ saying that it was no longer to be offered.
I was bummed to say the least, and I did mention it in my feedback at the end of the cruise, as one of the reasons that I pay extra to book Haven class is so that I don't have to worry about getting into shows etc.
