Flew in last year on my own, no probs.
If you are happy flying in the vicinity of other aircraft, keeping your own lookout and not being told what to do by someone one the ground you should not have any problems at all.
Those who can't cope unless someone is on the radio telling them what to do may have more of a problem.
As Mariner9 says the departure is where it gets more interesting as the departures are crammed into a smaller timeframe than the arrivals. The efficient despatch process using 2 runways puts people in the air at a high rate and the slower ones get overtaken by the quicker on climb-out.
I tend to monitor the queue taxying and wit for it to reduce a bit.
