I just secured a boarding group which gave me an estimated time of exactly when my Space 2020 lunch is scheduled. Has anyone else had this issue and tell me how it went?
Honestly, I think your bg will end up being later than what the estimated time they gave you. But if it’s not, people here say to go to your dining reservation on time then to Remy. Let them know you had a dining reservation and they should still let you on. Many here said this is what they did and had no problems.
I went to my Remy BG six hours later than I was supposed to and didn't give an excuse and they let me on. Go to the lunch reservation on time and you should be fine. That one is harder for Disney to be flexible with.
I spoke with a CM back when ROTR was boarding group only, they said to always prioritize a paid event.
Sometimes the CM will ask to see a screenshot but most times just telling them you had a conflicting reservation will be enough and they will wave you in.
Don't worry if you show up late for the BG. They are more concerned about people trying to get on early. If you can show you had an ADR, there will be no issue.
As noted Remy still brakes down. The week we were there, we rode it 3 different days. Our estimated times were off by 30 minutes to 2 hours.
