My wife and I are on the January 19 Wonder cruise and our documents arrived yesterday (December 10). However, the documents for each cruise seem to get mailed over a two week period between 4 and 6 weeks prior to departure. Other posts seem to suggest that it is almost random where, within that window, they arrive. However, you might give them a call if you don't receive anything within the next few days since your 1/11 cruise is only four weeks and 3 days away.
