Royal Caribbean cruise Deck 5 下午两点才能登船？

这个周末要去做cruise，第一次坐，很多事情不了解。
今天收到一封游轮公司的email, 说Deck 5的游客2点登机。具体内容如下：
Hello, this is Royal Caribbean International. We would like to provide you with important information regarding your sailing on January 25, 2016, onboard Majesty of the Seas. To enhance the check-in and boarding experience, we ask that guests arrive to the terminal based on the following times.

这是说 Deck 5的人必须在2点以后才能登船吗？ 还是说我也可以早到？因为想早点上船，早点开始享受起来了
