I spent today using a Greater Manchester Wayfarer. I hadn't heard of this until recently, so I thought I'd try it.
https://tfgm.com/tickets-and-passes/wayfarer-adultIt covers rail, bus and Metrolink services over quite a wide area. There are maps on the site. It costs £15.20.
I started at Marple and got a train to Piccadilly (195 107 if anyone is interested). I then got a tram to Altrincham, along the old MSJ&A route. I used the line a lot when it was heavy rail, but never before since it was converted. From Altrincham, I got a train to Stockport (150 113) and then changed to the Buxton line (150 146). I stopped there for lunch and returned to Piccadilly (150 110). Then a tram to Bury. Bought some black pudding at the marked and back to Piccadilly. Finally, a train to Rose Hill (195 128) and a bus (11542) for the last bit. In theory, I could go out again this evening, but I think I've had enough.
Perhaps everyone but me knew about the ticket, but if not, it's well worth looking into.
