You can book ADRs before the free dining offer comes out. You can book ADRs and not even have a trip planned. Nothing is stopping you from doing so. You can get free dining after booking ADRs.I admit that I am new to all of this, but if you wait to book how would you get the ADR's you wanted? I just booked mine on Saturday at 6:00AM and still had to give up some of the things I wanted in order to get in. If I waited even a few hours, I wouldn't have got it at all. So how do you wait to try and get free dining and then have restaurant availability?
Also, why would they offer free anything in the peak summer months? Why not wait if they are going to reduce free dining? Again, I am new to this so I may very well be missing something.
Just because it's the peak summer months in the parks doesn't mean it is in the hotels. The free summer offer was only for value resorts and only for counter service dining.
