Surprise date ideas

Katelyn • In a relationship with my best friend❤️
My boyfriend will be home on leave for the next couple of weeks and I want to surprise him with a date. Probably take him to dinner at our favorite restaurant then somthing else. Any ideas on what I should do? We already have a camping trip planned, we already have a baseball game planned. I wanna do somthing we don't usually do... We've gone mini golfing in the past, we've gone on hikes, been to museums. Maybe I'll make it a romantic night and make him dinner and light candles? Any suggestions ?
