We went in the rain.
Were you able to contact them by phone?! I wasn't able to go on tour and I was told they don't do refunds. :(
The Wendella office, a representative actual human, will call the # you provided in plenty of time. I had 1p on the 24th & called early. The lady told me I would have heard by 9a if it was canceled. . We went. It poured, they went out! Pretty miserable experience but hey that's Chicago weather!
