I was one of those waiting at Tytherington - but gave up on it when it was half an hour late and headed back to my car parked around the corner. It arrived minutes later and I ended up following it out of Macclesfield - Doh!
However, the other experiment I was wondering about was to use the P+R at Ashton - so I shifted to that option. Apart from struggling to find my way into it, and going to the one that doesn't have EV chargers - it looks a good option. At the very least - you know a tram will show up and if there is a problem there will be information on the boards or the app to tell you so. Standing at a bus stop in the middle of Cheshire with no info is no fun at all.
