If this is happening it is on the CM for allowing this lunacy.
1- they do not give RS for NRJ except in very specific cases that the CM allows it. There is no height limit and it is not scary.
2 - the CM should not be giving a RS to Dad at all for NRJ because he cannot even produce any child who would be too short or too scared or sleeping, as Mom and taller child are currently on another ride.
3- the CM should not have given Mom the RS for Dad for FoP because he did not have a FP. This is the rule, although apparent it has been rarely enforced. At DL where we have had digital RS for maybe a year, this is always enforced. At least in our experience.
So no, even with the current system, the way you described should not actually ever be happening. If it is, I put the blame on the CM’s for allowing that to happen. With the new system no chance that will happen.
And shame on the family who would do this because they are very clearly knowingly abusing the system.
This is why we can’t have nice things.
I'm sure there are people doing this. Thread I linked to above had somebody bragging about doing it because they throught tiers were absurd. Ironically there were people in there saying that people doing stuff like that would get the system changed... and here we are.
Based on what you said and the rumors for WDW, it sounds like they are just going to implement in WDW the exact system they currently have in DLR and if its been running there a year I'd expect most of the kinks have been worked out. Still would have been nice to give people notice so they could plan.
