So glad we were able to go yesterday and ride Tron. It's a fantastic ride. We were over an hour late to our arrival window and thought we'd have a hard time getting in but the CM let us right in without issue.
Disney announced that TRON will operate in a "soft opening" mode from March 20 through April 2. The soft open will use VQ and paid ILL selections. The VQ times are 7 am (from anywhere must have MK park reservation) and 1 pm (must have entered the MK to try).
