Long distance

My boyfriend and I have a very strong and healthy relationship. The only thing that sucks is that I live across the country from him. But we have made it work and it's great. We also have an awesome sex life. So when we are together, it's great. But I really wanna surprise him next time I see him, and spice things up. I leave next week to visit him for a week, any tips to spice up our time together ?? Thanks!!
