Valentine's Gift Advice?

So Valentine's Day is coming next month and me and my boyfriend decided we're gonna celebrate the weekend after since we both work. We already have plans to go see the new fifty shades and I'm really excited even though he hates it. I want to book a hotel room and put on some new sexy lingerie to try treat him for taking me to the movie. I think it sounds like a fun idea on paper, but sexy panties don't really interest him...I don't want to do this all to feel bad in the end when he doesn't get excited... I can't decide if I should just go for it and order or mention the idea to him and ruin the surprise? I don't know who to talk to about this so any advice would be stellar!!
