The Tink zip line goes right over Tomorrowland Terrace.
Before they started doing dessert buffets there, yuo could just walk up and station yourself right underneath the line so she’d go right overhead.
There’s also the walkway behind the right side popcorn stand that reconnects at the bridge into Tomorrowland from the Hub. Again, you can get right underneath the line there too.
I’d suggest downloading either my Wishes or Holiday Wishes videos to see what we’re talking about.
