Don't worry it's easy peasy! We took the
DCL bus to Port Canaveral back in March and it was 2 of us as well.
But question first - Not sure if you booked the DCL transport yet, if no, just want to make sure you know this is a service that requires reservation and must be added to your cruise reservation in advance.
If you already have a reservation, here's some tips and my experience -
When you take the shuttle from the hotel back to MCO, ask them to take you to Terminal B Level 1 for ground transportation. It depends on where the shuttle drops you off, the DCL transport check-in is further towards middle/front of the terminal, so if they drop you off at the end of the terminal, just keep walking inside the terminal and eventually you should see DCL bus check-in on your left. From there, the CMs will have you drop off your luggage in a specific area and you will not see them again until you're on the ship. So make sure you have everything you need with you.
We had 1230 PAT I think, and we took the hotel shuttle (also near MCO) around 10am. I can't remember the exact time, but I'm pretty sure we got on the bus and left MCO just before 11am and arrived PC a little after noon. One of the nice things about DCL bus is that, even if you're early for your PAT they will still let you go inside the terminal and check in (someone corrects me if that's no longer the case). I remember when we got to PC, the sign at the gate had displayed they were allowing 1215 PAT or earlier to go in. Had we taken an Uber/Lyft and arrive at the same time, we would have to wait until they let 1230 PAT in, so that's a nice little perk.
It was our first time taking the DCL bus to the port, easy and smooth experience, I would do that again.
