We have an 8:05a reservation at Oga’s Cantina in a couple of weeks, on days with 8a opening. Anyone know whether we’ll be able to get past the crowds/ropes, or should we just count on heading there first? Or, would you advise I cancel and rope drop a ride instead?
With an 8:05am reservation, you will not be admitted into SW:GE early. It opens at the same time as the park. If you booked this just to get early access then it isn’t worth it. If you want to start your day with a fun cocktail - that’s a different story! 
I also have an 8:05 ADR. I believe we can go to the early breakfast line to skip the hoards at the tapstiles.
