The time you can board your cruise varies depending on what kind of stateroom you have and what time your cruise departs.
You can always check the Celebrity Cruises mobile app to confirm what time your ship sets sail on embarkation day. Be prepared for an initial rush when boarding begins and another rush right after lunch.
To avoid long lines at security and the check-in desk, plan on getting there right when boarding begins. Lines also tend to be much shorter during the last hour of boarding, but then you’ll be missing out on a few hours on board on embarkation day!
If you’re planning to arrive later, make sure you know when embarkation check-in ends, as this is usually before your ship sets sail. For coast guard purposes, the check-in time ends earlier, and if you get there after that cut-off time you won’t be able to board, even if the ship hasn’t pulled away from port yet.
