Preparing for my trip

I’m going next weekend and I can’t wait. The last time I went I was a child so I didn’t have to worry about anything. But I’m not too sure what to bring or even the best thing to wear. I will definitely be in my trainers but I can’t wear trousers and have to wear skirts or dresses but I’m worried this may be a problem. I am a little worried as well, since even though I am entitled to a red RAP there are none available for when I go but I’m still going and I hope to enjoy my trip as much as possible as Alton Towers is my special interest.
