still seasonal. When we were there in June, a fairly heavy time, it was only open for lunch on the weekend. The only way to know is to check the times guide when you get into the park.
1) It is open, but only seasonally.
2) In other words, when WDW is really busy.
3) This is a blessing in disguise.
4) If it were not for ABC Commissary, TT would be the worst eatery.
{IMHO}
the tavern is keeping to seasonal times and that usually means when the park is busiest. it does seem the best way of knowing is to check the guide on the day.
