No, it is pretty easy.
Basically the luggage claim is on the opposite side of the airport from ME. So, you traipse through the airport to Baggage Claim. Get your bags. Go to the elevator that is nearby (it is huge and much easier than the escalator with multiple bags). Take the elevator up to the main level. Walk your bags across the main level to the other side. Get into an elevator on the other side and down to the ME level, then walk to ME.
A word of advice: MCO has lots of CARPET. Even the best rolling suitcases don't always like carpet, and even if they are fine with it the resistance means it is hard for the human hauling the bags. BUT there is a tile perimeter of sorts.
On the baggage claim level, we get off the carpet ASAP and onto the tile (the carpet is around the baggage claim things themselves; the tile is closer to the outer wall along where the elevator is). A few more steps since we're using perpendicular lines, but the ease of the tile makes it worth it.
Once you are on the main level, instead of going straight across (lots of carpet, and people), go to the margins... basically, if you skirt around closer to the shops there is tile. You can use tile for most but not all of the way to get across. There will be a couple bands of carpet to navigate, but they are short.
As you can see in this picture, lots of carpet, but also some tile:

MCO has good info on getting around the airport:
https://www.orlandoairports.net/getting-around-mco/
WestJet comes in on side A. you will come in to the main terminal from the gates on level 3, follow the signs to side A baggage claim (which is on level 2, one level down). Then the up and over and down (back up to level 3, across level 3 to get to side B, then down to level 1 where ground transportation - ME - is).
