I love using touring plans -- i believe most of their estimated wait times are reasonable. probably except rides like FOP and what will be the new TS land - simply because there is not a good hx of wait times. It helps especially if you want to include shows. It is fun just to play around with it. If you have a trip planned and in your touring plans system they will email you if there are changes in park crowds and/or park hours.
It has the ADR finder/notifier so if you are looking at a particular restaurant and there is nothing you can sign up and get a text when a reservation opens up.
I thought that the room request feature through touring plans did not work for
DVC reservations. I could have sworn that i read that. And from the results that i had on my last trip - I requested BWV high floor area towards swan and dolphin (and away from that creepy clown pool). I got the opposite -- first floor right facing the pool. They did accommodate and were able to change us.
