yep - we do provide our own separation (normally with altitude), but we check on descent with FRS and Company Radio to see who is likely to be around when we arrive.
I have been #5 holding overhead when runway works have meant that no taxiways or extra parking are available.
Yes - expensive to hold - but we do coordinate with our Dispatchers who invariably request us to wait and not divert..fuel is cheap here ( JetA1 is 50C/ US gallon...car gas 25c/litre - V8s rule !!)
