Toast will still be an option they have the breads out and you just toast them yourselves using the machines
As well as the usual pastries and all the other continental sundries.
Having spoken with out Disney agent she said that the DLH will always be offering hot breakfast and will not change.
The NY, NPB and SL will only offer hot options at their club level rooms, so that's Empire Club, Compass Club and Golden Forest.
She advised that if you have made a booking it should state the type of breakfast on it so if the hotel NY had hot breakfast it would say breakfast type - American so technically they may still have to honor this. Perhaps they will accommodate you in the club level breakfast rooms?
Sorry I know this is likely not very helpful we have never had a hot breakfast before but the again we have never stayed at the NYH so didn't realize it was standard there as none of the other hotels we stayed at had it.
