Ridiculously cheap. £20 to watch the worlds best riders in a world class stadium with a roof. Plus a fanzone, plus fireworks.
Yet the armchair viewers want to move it to Belle Vue, which they also won't attend because of the ticket prices/hotel prices/weather.
It's never been announced at the event. Usually announced the Monday after the event but last year they asked you to register interest for 2024 and they are doing again this year.
Premier Inn prices were at their cheapest on Saturday but gone up a bit since then. I was staying in the bay but changed on Saturday to stay at Premier Inn Stadium.
When I looked at staying in Manchester for SON the city hotel prices were comparable to Cardiff. I didn't go because of the absolutely rediculous ticket prices.
Use something like Trivago for price comparisons. There are much cheaper options and even hotels like Mercure Cardiff Holland House Hotel & Spa, Park Plaza and Hilton are cheaper than Ibis Budget.
