My summer fling (F20) an I (M20) are talking again after a big fight, but i need some advise about labor day.

A week ago I submitted a post about how I messed up and said something I shouldn't have and hurt a previous romantic interest, well my summer fling. We have since again started talking. Although, we aren't the same as we were 17 days ago. I'm no longer the first person she goes to to tell me about what happened to her. She no longer texts me back right away. There is also no longer any sexual or flirtatious innuendos. This is all fine, I accept that I fucked up and she may still have some underlying resentment towards me. I'm just happy we're talking again.

Before our fight, we had made plans to fly her across the country to come see me in Arizona and drive to California to spend a few days there for Labor Day. We briefly talked about it and she is still flying out here. I haven't yet asked her if she's coming here to see me or just because I bought her the ticket. This is where I need some advise. I told her I'd like to use this time reconnect and rebuild some of what we had lost; maybe even make everything up to her. Say things went really well, and we start acting the way were before my mistake; would I complicate things if I tried to get intimate with her? I'm not talking sex, I would never do that to her unless she really wanted it; but if I were to try to hold her hand, put my arm around her, or something along those lines. Also, she's never been to Disneyland so I'm going to surprise her on the last day with a trip to Disneyland. I want her to see the firework show and castle projection show. Would it be too much if I went in for a kiss? Lastly, when we originally planned this, I only booked for a single queen size bed. Should I sleep in the same bed as her like originally planned or sleep on the floor?

Should I just not try anything and enjoy the time we have together?

Just so all of you know, I do still genuinely have feelings for this girl. I know she was just a summer fling, but she's managed to get me to open up to her in ways no other woman has. She knows so much about me and I know so much about her. The only reason we ended what we had is because I had to fly 2000 miles away for college.

Any thoughts or opinions are greatly appreciated!

TL;DR Me and this girl are talking again after a fight. We are going on vacation together. Should I make a move? or should I just try and keep it all platonic? or see what she does?
