Background info

So I've been on a date with this girl, I took the advice of the RP and got plates as I'm normally prone to Oneitis and being loyal in the talking stage which I now realise is silly. For the 1st date I took the tram to her area and got some ice cream and took a walk in the park, did some flirting but honestly I didn't kiss close only hugged and we didn't have as much kino as i hoped we would but that's my fault.

So I know the advice that you should wait for her to get back to you after the first date however I was in a rush to see whether she is still an option or if I should next her and focus on my other plate who has high interest for me, so I messaged her saying "I had a good time and it was nice getting more familiar with u" she replied saying "yeah ur really chill". I wasn't too pleased with her response but I still asked if she's free this week, she said she has university stuff to sort out this weekend but next Tuesday is good. I suggested the cinema as I have tickets but she said "nah I feel like it is too hot for that in This weather but we can do something else" so I said fair enough and suggested the funfair and she said "yeah sure that sounds fun not going to lie".

Question

So my question is considering how the first date was a bit lacklustre from a RP perspective what should I do on the funfair date to make her think of me in a more sexual way and boost my chances of scoring, I think she's attracted to me since she wants to go on another one but I know if I don't escalate I'm at risk of being friendzoned.
