Narrative:

Landed runway 9L ord and taxied via standard routing to southport. At entrance to southport; ground control directed us to wait while ramp control (on our 2nd radio) directed other aircraft to wait for us. Very confusing that ramp and ATC instructions were not coordinated. We followed the ground controller's instructions but not without a lot of confusion.arriving to gate; almost all other aircraft in alleyway were facing the other direction to leave via the southport. 747 had the entirety of the northport blocked; which I am sure added to the confusion. Numerous vehicles crossed in front of us as we were trying to taxi in.most dangerous was first; the supertug [that] came into our restricted zone requiring us to stop. Then a baggage tug/cart came in again requiring us to stop. Finally; another baggage tug/cart blasted past us down the roadway between the ramp and the alleyway. I completely lost sight of this vehicle as it crossed under our nose. Not one wing walker to be seen/found! I stopped until I saw a wing walker emerge; and only then did I retry to pull into our parking spot.oh by the way; it was snowing lightly (temperature about 34 fahrenheit) and everything; especially any painted surface; was slick! Really hard to get stopped! And starting a jet aircraft requires some increase in thrust; especially single engine; bad for all behind us. We can repair bent metal; but if someone got hurt due to the lack of foresight; poor planning; disregard for procedures; laziness; whatever the reason; it would have been absolutely unacceptable!if I need to sit in the penalty box 20 minutes while ramp clears up the mess; so be it. I won't like it and neither will our customers; but it's better than getting someone hurt on slick tarmac in a confused environment!
