We haven't been yet, but we're going the same week. I have had a pretty easy time switching around ADRs, so I think even with FD crowds will be light. Plus there are two deals at that time - you can do either FD or the 4/3 or 5/2 deal. We had our pick of times at quite a few places, including Akershus, Tony's, Sci Fi, 50s Prime Time, Kona, The Wave, Marrakesh, Biergarten, Boma, etc. So I think she COULD wing it, but it seems simpler to just have ADRs so she doesn't have to haul around from place to place trying to figure out what's available and when.
