Our plan is to keep an eye on the app and wait for ROTR to go down. It nearly always does, usually in the afternoon. Then go and wait for it to reopen, and you'll be nearly in the front of the line and get on with minimal wait.
Granted, it may not work, but it's worked for us about 4 out of the last 5 visits. Typically nowadays, it usually only breaks down for about 30-45 min before it reopens.
