We have not gone to WDW since they added the umbrella stands - we have gone when we had the GAC, did the card with the return times written in (that was a mess), and have gone to the ride to get a return time.
Last few years we have been going to DLR and they have the stands - what I am guessing is the equivalent of the umbrella stands at WDW. For us this is the best version of the program. We can go to any stand to sign up, add people, and get return times. At the ride we just scan in like a FP and go.
At WDW DD had trouble understanding when we had to go get the return time at the actual ride. Last time we went to WDW I had to be the runner (DH has a knee replacement so he is more of a hobbler

)
and some CMs would tell me I had to have DD there to get the return time.
I had read about the GS umbrella stands a while back and got pretty excited since we are planning a trip in May. I will just have to adjust our plans and see how the new policy will affect how we tour. Really wish they would have the program set up like at DLR.
