Having just come back from a trip, I never waited more than five minutes for any ride using Genie+. Most of the return times were instant so I'd book a ride, tap in, and book the next as I walked through the queue of the ride I just tapped in and smashed through all the rides in each park before noon. Yes it's annoying you have to pay for something which was once free, but personally I thought Genie+ worked great and is an improvement over FP+. If you don't want to wait in long lines then bite the bullet and pay for it. Time is money in a theme park.
