This. One million times this. When I first started dragging my partner, Ryan, on Disney trips, although by the end of the first trip (to DL at the time) he loved it--and at the end of the first day cried at the end of Fantasmic--he eventually put his foot down. He told me they way I liked to do Disney wasn't the way HE liked to do Disney, and that I was ruining the experience for him by trying to force him to love Disney the way that I do, rather than the way that he does. I'm a commando, rope drop to midnight, ride my favorites repeatedly, run across the parks like a marathoner Disney parks fan. He's a resort-loving, pool hounding, show up at MK at 3, give me my five favorite rides per trip and I'm good, inveterate bench-sitting people-watcher Disney parks fan. Our trips got so much better when I stopped trying to make him be the kind of fan that I am. And he was trying to tell me that from day one. (Literally, when I dragged him up Main Street when he wanted to stop and watch the band play.)
OP, your BF is NOT (I assure you, absolutely NOT) going to share all of your same loves, likes, and preferences at WDW. If you don't give him space from the start to both let you know what he's enjoying and to lead sometimes and not just follow you around everywhere, you're setting yourself up for disaster and Disney heartache. Take it from someone who's had that mid-trip screaming match over my plans vs his plans and thankfully lost.
