I did it with my other half (we got a voucher as a Xmas pressie) and while it was quite good fun, we both felt motion sick for the rest of the day.
I get dizzy really easily on fairground rides etc. so expected it. What I didn’t expect though was just getting in the thing made me dizzy, as it damps sound so much – kinda like an anechoic chamber.
It was over in about 20 secs max and was slightly disappointing for an hours drive each way and then sitting around for an hour before our ‘ride’.
You could also do a version where they chuck in several buckets of water, you aren’t strapped in and they roll you down. As you go, you slide around on the water, but stay the right way up. If I’d have known you could do that as an option, I’d have done that one instead.
