I do think how to book your virtual queue spot will be interesting - and do they let those staying on property have special access to get a spot in the queue? I agree with the challenge if they are all gone by 6:30am .... but also think the idea of standing in a 5 hour line to just get into a land sounds pretty terrible and definitely not something Disney wants - they want you out and in the shops and buying food, etc. And just the management of a line that long all day every day
probably not perfect solution but I really can't see them just doing a straight up queue
