Interestingly enough, in some of the pre-sale literature on VWL, one of the amenities they had listed was 24 hour room service, but that never materialized. I am trying to remember if there was 24 hour room service at the beach club when we stayed there, but I can't remember for the life of me right now. I do remember there being 24 hour room service in the contemporary tower when I stayed there (ordered some chicken soup at 2am when i was very sick and it felt great on my throat) but that was around 3 years ago.
Since BWV and BWI share services, I would be surprised if they were only cutting room service hours at the BW and not the other Epcot area resorts (if not at all of the other deluxe resorts as well). Maybe only the GF is retaining 24 hour room service (since they are also the only ones with a 24 hour snack bar? Am I right on that?)
