Steve. I am now confused? Who on earth is telling you to buy a season ticket? Who is telling you that you must attend a concert/workshop/whatever?
If you want to spend a week in Sidmouth ....Fine
If you want to attend events.....Fine
If you want to sit on the Prom playing tunes.....Fine
Who exactly is telling you that you can't do what you want to do?
To my knowledge, the people I know turn up Sidmouth to say hello to old mates, hopefully make new ones, play tunes, sing songs, see some top name artists, whilst having a holiday in a very pretty town. What's your problem with that?
I'll repeat myself. If you don't approve, go somewhere else. There are thousands of people who will turn up, as they do every year. Your abscence won't be missed.
