As I recall there were some US specific items for sale on Independence Day (US flags and shirts, pretty much only US-specific things that ROM has in its database). So, there are *some* national holiday specific events. But Labor Day? Labor Day is a joke of a holiday.
You mean Labor Day that is on wrong day?
I never got my sombrero thanks to them not doin' Sinko de Mayo... not sure why, they in EU are not celebrating neither this US holiday...
On sarcastic note, I for one would be surprised if you got double (or higher) XP weekend. Those did not happen in a while... and in the time of Frogster NA it was almost every weekend...
BTW, do you ever check your messages?
