Any tips on planning an exciting date?

So I'm new to this site, and stumbled across it when looking for help with my situation. A few months ago I got controlling and possessive of the girl I'm with, and made her want space. Since that, I've changed some things in my life and given her that space. The spark has been reignited and things are going well. I just need an idea for a memorable date tomorrow night. We've recently gone out for a meal and have done the staying in and having lots of sex this week. I have from about 7pm, but am clueless with what to do. Any general tips on how to keep things exciting would also be appreciated.
