During regular park hours, your options are joining a Virtual Queue or purchasing either Multi Pass LL (Tiana) or Single Pass LL (Tron).
During
MNSSHP both lines are standby. We were able to easily get on both during the party. Tiana was 20ish minutes, I think, right after the first parade (we watched from that corner and then jetted over to Tiana as soon as the parade was done going by). Tron was at the end of the night (11:40ish) and a very short wait.
