I was there... honestly, very underwhelming and I didn't particularly enjoy it for the most part.
Main reason for me was that the atmosphere felt strange, I can't quite put my finger on what it was, but it just wasn't very fun. I got my last ride around to say goodbye which was nice for sentimental reasons, although I did queue for almost an hour... and otherwise I was somewhat disappointed.
Car 1 (red) stopped just before the return spiral, and it took quite a while for them to fix it, but to their credit they had plenty of staff looking at it (including Mr Hygate) but they did have to evac.
Around the start they had a band playing with basically no one watching as far as I could tell, a shame as they weren't bad. The supercar lineup consisted of a Ferrari and an Audi R8 that both left before 9pm. The music after the band had finished was very loud around the station, and then stopped around 8:30pm ish? So it was awkwardly quiet with the odd noise from people.
Asked whether there was a non-alcoholic alternative for the free prosecco as I don't drink, was given a puzzled look and told "I don't know, sorry".
I'd been at the Pleasure Beach all day so I was slightly tired and the weather was poor which didn't help things. I also went alone and didn't see anyone I know, so again, that didn't help. Many of the people in attendance were not at all who I expected.
First BPB event I've ever done, and I had very high expectations after having been at the Nemesis Reborn VIP event
and having heard much praise on previous events there, so it absolutely won't stop me from doing more in the future, just my thoughts. Was it worth the (high) £50 ticket? Not for me.
Edit: And just while I remember, did Grand National a couple of times during the day, and as I haven't done it for at least 15 years I can't really remember how rough it used to be, but I had a back row ride just before 5pm and it was one of the most painful and violent rides on a roller coaster that I've ever had.
(it seems after searching, this has been the case for years, I just didn't quite realise)
