First-timer question. What is your wait time threshold for doing a LL vs the standby line? I assume that even the LL has some wait (5-10 min??) so you'll waste the LL if you use it when the standby time is short. My question is how short? For context, we're going the week before Christmas with 2 kids (7 and 8 yo) and we have many days in the parks, so not too worried about jamming it all in one day.
