Modifying BG1 & the 120 minute rule

I’m at 63 day until WDW. I was just wondering… If I ‘modify’ a LL with MDE the 120 minute rule does NOT reset. Is this also true if I modify using BG1?

Yes it’s the same. BG1 is simply another interface for MDE. Booking rules for G+ are the same no matter which you use.
