Would this be impossible?

Most restaurants give you a 15 minute grace period. It might not be the most polite thing to do (by planning on being late) but I would totally do it to get to see wishes! Just watch them from closer to the fantasyland side of the hub (instead of like dead center) and you'll make it by like 9:25-9:30 and they'll seat you.

It is true, if it is possible the restaurant will seat you past your ADR time, but it is not a promise. The combination of a late ADR and it being a late ADR at BOG makes the "grace" that really is not a policy, problematic.

OP- you need to decide which is more important: BOG dinner or Wishes. UNder these conditions, you probably cannot do both. You can chance arriving late for dinner, but you need to accept that you may be turned away, and that you will be charge the no show fee for your party..

They'll take you late.

This is not true. First, Disney has begun to get "wise" to folks overlapping their plans and making ADR's that they cannot arrive on time for, so while they will set guests if they can, they do not always "wait" for you. When you tell people they will do so, you should keep in mind the restaurant they want to be late for. BOG is the big issue here. They are in constant demand and have turned late arrivals away.
