Let's have a poll.
It's been ages since any ranking has gone on around this forum.
Oh please not another forum ranking!
I personally feel that there is a lot of potential for the UK theme park market, the trouble is that Merlin has monopolised the market in this country and chipped away at it product. Back in the 80's, 90's it was a race to the top, who could build the biggest, fastest ride, now a-days it's now a race to the bottom.
Yes times change, you need to bring in new rides and attractions, but also you also need to keep some of the old classics. As far as I'm concern in addition to your rollercoasters, all themeparks should at least contain a log flume, an old fashion carousel, rapids, a good indoor dark ride or two.
OK the themeing is not great at Alton Towers, but then it never was back in the day. However it did seem a lot tidier and cleaner back then.
