Right now, the furthest out URComped goes is 13/14 months (with the exception of a meet-up cruise).

Casinos do not like to offer sailings that far out, because a lot of gambling is done with discretionary income. So much can change to someone's assets over 2 years. A person's business could go under, someone could lose a job, or something else could change someone's financial ability to play in the casino. 

Cruise Lines initially limited URComped to only booking 3-6 months out. Thankfully, as we built our reputation, we're now able to book 13-14 months out.
