I plan to take the 7:15 am Buquebus boat service from Buenos Aires to Montevideo.

The Buenos Aires terminal is open Monday to Monday from 6:30am till 23:30pm all year

It is highly recommended to be 2 hours prior the departure of the ship to make the Check In, migrations and boarding. If you are travelling with a car, it is imperative to be at the Terminal 2hs before departure because the cars must be loaded before passengers. It is important to take into account that in high peak seasons all the processes can take longer than expected.
The first paragraph says that the Buenos Aires terminal is closed before 6:30 am but the last paragraph says it is recommended to arrive two hours prior to the departure time of the boat.
Is there any point in showing up before 6:30 am at Buenos Aires terminal when taking the 7:15 am Buquebus boat service from Buenos Aires to Montevideo? (e.g., clearing the immigration before boarding, if the immigration counter is open).
