We live fairly near to an English Heritage place (Wrest Park, if you know it). The entrance is through the old walled gardens, where there's a café, gift shop, loos and a playground. Diagram attached.
When the DC were little I'd take them to play in the playground and we'd buy drinks, ice creams, often lunch. The ticket office was after the cafe area so you'd only have to pay if you wanted to visit the house and parkland.
Today was MIL's birthday so we thought we'd take her to the café. We had other plans afterwards so didn't want to visit the house and parkland. They've now moved the ticket office so you have to pay to access the café area. £19+ for one adult (DH and I are EH members).
WIBU to give that a pass and go to a café where you don't have to pay nearly £20 just to get in?
YABU - it makes sense for them to move the ticket office so people have to pay to go to the café.
YANBU - this is a daft move that will stop people spending money they otherwise wouldn't have done.
