My suggestion is yes. Parks may close. Even if they don’t the chance of storms shutting down many rides is high. Too expensive a tour to take a chance.We arrive on Friday for a week... We have our rain jackets and determined to have an awesome time... My biggest question is we have the Ultimate Day of Thrills VIP tour on Monday and wondering if I should cancel that so we get a full refund since we are still within the full refund period...
