OK, MCO hotel to WDW resort/breakfast = Uber
WDW resort to MCO hotel = Uber
MCO hotel to MCO = shuttle
MCO to port =
DCL transfer?
That's a lot of traveling that day. It's about one hour MCO/WDW; as well as MCO/port. You'd have to build that into the schedule. Plus allow time at MCO to get on the bus to the port (could be a line).
Working backwards (figuring you want to arrive at the port around 1:00)
12:00-1:00 travel MCO to port
11:30-12:00 load up on DCL bus at MCO
11:00-11:30 shuttle from MCO hotel to MCO
10:00-11:00 Uber WDW resort to MCO hotel
8:00-10:00 breakfast
7:00-8:00 Uber MCO hotel to WDW resort
How long do you need to get ready in the morning (including packing up)?
