This was the first year in 15 years we have not visited the FWF.
General tips:
You can easily make a meal out of snacking throughout the day. We don't make any ADRs when we do FWF.
DH and I like to share each dish so that we can try even more! If I ate a whole one myself, I'd probably only have room for around 3 total. Even though each is a little bit of food, it all adds up.
I don't find the drinks to be a good value. I'd rather get the "regular" (i.e. non FWF drinks) as we tour World Showcase (like the Grand Marnier slushie in France or a glass of wine in Italy).
I like to read other people's reviews of the food. I think it helps to know which foods aren't worth trying.
The booths open when WS opens (usually 11am). We like to hit the booths early as crowds increase throughout the day.
Avoid weekends if you want to avoid huge crowds.
The drunks make themselves know later in the day. When that happens it's usually our cue to leave. I enjoy drinks/wine just as much as they do, but I don't find getting drunk and stumbling around in Disney to be fun. I don't enjoy watching others do it either.
We usually do two EP days during FWF. That way we can try different foods on day 2 that we were too full to try on day 1.
Have a great time!
