Well, I think one thing to keep in mind is that Chefs de France is located in a park (epcot) where it would be unnatural to expect people to dress up given they'll be going on rides and wearing those clothes all day. I think if Chef de France were located at one of the resorts, it would probably be a dressier affair (or at least I think it should be based on the decor).
The fact is that what other people wear does affect the ambiance, just like what the room looks like affects the ambiance. Imagine if Cinderalla had gone to the ball to find Prince charming and all his guests in shorts and flip flops! Lol. Not quite as romantic an affair I would venture to say.
With that said, I do think there is some potential that this rule change might (*might*) be a good thing. Perhaps, Disney has changed the rules so that it's easier for them to enforce the rules. If that's the case and if they actually enforce the rules after this rule change, than I think I can handle a few shorts on casual nights
. They might also use this change to actually enforce no shorts on semi-formal and formal nights. I would very much approve if it worked out that way. I know, this is probably wishful thinking on my part, but I'm allowed to hope for the best. I guess we'll all see how this works out soon enough.
PS: How did everyone learn about this rule change? I checked DCL's FAQ's yesterday and they still list the old dress code. Anyone know if this is a for sure thing or is it just something they're talking about?
