AK closes at 7 the day we’ll be there and we have an ADR for Rainforest Cafe at the park for 7. I have read about horrible waits even with an ADR (only going because my daughter will love it) and I’m afraid if it takes 2 hours that the buses to Pop Century won’t pick us up. I’m not willing to take a bus elsewhere and transfer.
Disney will not leave you stranded. Also keep in mind there is a Disney Springs RFC too.
You probably wont have a problem but if it looks like it is going to be long I would call an Uber. Never had a problem with Uber. Great people, cheap service, and they arrive in just a few min. Good luck!
