Tickets to a game

So I have tickets to a game for me and my girlfriend to watch, and love the idea of us getting to totally have a good time with each other, though it is like I am trying to find the best way to frame things where it is possible for us to have a good time, this is one of them, I think it would be super sweet, and something we could really like doing together, though I am trying to get things down in terms of the "I got tickets" message I plan to set us up with, how best to surprise her?

Thx for any info in advance.
