We used
Genie+ at DLR last summer and I was able to enter both LL and ILL entrances with him. All I said was “I’m not riding” and they said just use the exit at the end. It’s never a big deal at DLR but I know WDW is a whole different animal. DLR is a much more laid back experience in general.
Also, I think they saw the look of fear in my eyes like I definitely am not riding this ride! Lol. They knew I wasn’t about to sneak on.
