Help with kids coming in super hyped up

Hi guys! I'm looking for some advice with a sibling set in my dayhome. They have been attending since the beginning of January, a 6yo boy and 3yo girl. When they arrive they both take off from their parents at the car and run screaming to the door and start banging and kicking the door. The parents both say nothing when this happens. I have asked them to not do this, just knock once or ring the doorbell once. Then when they come in they throw and kick their belongings all around and I have to repeatedly ask them to hang their things nicely and put their boots away. Then when they finally start to play, they are both running around screaming and jumping on furniture, throwing things, etc. I have provocations set up every morning in different play areas to try to wrangle them into more indoor appropriate types of play, but the first 15 minutes of every day is just WILD. I try to explain my expectations to these children every morning but they always start every day like this.

I also encorporate a lot of outdoor play during the day and try to encorporate games that allow for the kids to have an appropriate outlet for all that energy but every morning it's the same thing with screaming and running and chaos. Other kids are getting hurt/upset and my own children have started anxiously asking if these two are coming each day, even on the weekends, as their entrances are stressing them out too.

I'm just not sure what to do to make the transition from home to dayhome calmer and smoother. Any advice?

Editing to add: the one parent does not even come in the house at drop off. I open the door and they say bye and walk away. If the other parent does drop off, they don't say anything about their behavior.
