I am with AR on this one. I have spent many a mid-after noon walking the mating yards and sitting in camp chair observing the comings and going. In my observations, I also of the opinion that "mating swarms" are a myth. The queens I see leave alone and return alone.
That said, I noted there is definitely much more activity and attentiveness by the bees at the entrance of the nuc or hive when she is out frolicking. It is like a big send off party, quite a few bees ushering her out and bidding farewell. Then they just hang out on the porch like an expectant welcoming party lined up at the terminal gate waiting for mom's airplane to land.
That is generally what I observe. That said, there have been a few outliers. For example some are followed all the way back by a bunch of drones. I have seen her hit the grass short of the hive on the way back and 5 or 10 bees land around her and nurture. So there may be a few, a small entourage, that follow or guide her. Certainly not a swarm of any noticeable size though.
Bees will be Bees
