Congratulations on booking your cruise.
There is a thread on Page 1 of this
DCL Forum - “What I need…” (photo below to show you what you are looking for). It should help with knowing what to have on hand at check-in time (next year

sounds so long away).
Some of it is outdated (all the temporary C19 procedures).
Your booking email from DCL should tell you when check-in is.
Put the DCL app on your phone for a countdown.
When you get close to the 30-day mark, remember check-in starts as soon as that day hits (one second after midnight Orlando time). You don’t have to stay up unless you want an earlier Port Arrival Time or maybe a Royal party that needs tickets (I don’t know that detail).
