You will not be able to go directly to the line for the buses.
You will go to the ME counter. Have your baggage claim tickets ready to give to the CM. They may also ask you to describe your bags, or give you a picture of several bags and ask you to choose the picture that most closely resembles your bags.
They will call down to the baggage claim area with the info and there will be people pulling your bags and getting them for transfer and tagging them for your resort.
I will tell you a long story that will ease your mind.
The first year, I went down on the land/sea package and a couple near me had no clue what yellow baggage tags were, baggage claim tickets were, what flight they had come in on. They never read the wonderful information packet that the TA gave them after booking their trip. They had no idea what resort they were going to - they just kept saying all they knew was that they were going to Disney World and the
travel agent said Disney would take care of everything.
After finally remembering what airline they were on, the ME called the airline and was able to retrieve all their information, number of bags, baggage claim tickets, called CRO to find out what resort they were going to go to, and were in the process of getting hold of the cruise line to get their transfers for the next leg of their trip shipped to their resort, so they would have a much easier time.
So I wouldn't sweat it.
