I took this quote from your second post - it made me think of my DBF. It will be his first time when we go in August and he isn't really a Disney person and doesn't get overly excited about things but I want him to be excited for Disney! Since you said your bf wasn't so keen at first, were you surprised by how much he enjoyed himself at Disney? I'm really hoping my BF surprises both me and himself with how much fun he'll have! It's a little frustrating that I'm so excited and he's not. Any words of advice for me?
Heather, you are in the exact same boat I was in before my trip. I was super excited about everything, and would often tell him about my plans, but he really wasn't that interested. He's also not much of a Disney fan and hasn't been back to WDW since he was a little kid, and he barely remembers THAT trip.
I say try to plan the trip around him also. Maybe tell him about Hidden Mickey's and how it's like a scavenger hunt when you're in line. See if he's interested in that. When you go shopping, allow him to go off on his own and do his thing if he's not interested. No reason to keep him bored and following you around.
You know what he's actually interested in, so make it a point to point those things out. As a computer engineer, Andrew is very interested in programming, which is why Turtle Talk with Crush really blew his mind because he understood how complicated the programming must be. I also knew that he would not like to wake up EVERY DAY at 7am to get to a park at rope drop. So I planned plenty of days where we can sleep in and just relax or go around the resorts.
If he's into sports, maybe plan a lunch or dinner at the ESPN zone at the Boardwalk so he can catch a game.
If he's not into planning and prefer not to have to decide stuff, it's best to have an itinerary. You don't have to stick right to it, but you at least can answer the question "What next?" instead of saying, "I dunno, what do you want to do?".
I also know Andrew likes to drink, so I did my research on what the DIS recommends and had those in mind to recommend him, so we didn't have to spend time deciding if we wanted to try something. Get to know the menus of the restaurants in the parks, so you know what they're serving before you get into the lines.
If you plan to resort hop, get to know the transportation system and how they work, so you don't get stalled somewhere or even lost!
Since I'm sure you plan to souvenir shop, write down a list of what you're interested in getting, kind of like a shopping list. So all the merchandise doesn't distract you and you don't spend hours going through the shops just to "see what I might like". That'll cut down on browsing time and give you more time to just enjoy the parks.
I think what surprised me most with Andrew is the effort he put into enjoying himself. He really made an effort to appreciate what I appreciated and took the time to get to like the things that I liked, even if he wasn't sure about it before. He also really loved how prepared I was, that I knew exactly where we were going and that we had a plan. He's the indecisive type, so for me to lead the way was very good for him.
I think in the end, I wasn't super surprised. I was always worried he wouldn't have a good time in the parks, because he just wasn't interested, but he always reassured me that as long as I was having a good time, he would too. Instead of getting frustrated with your DBF, don't talk so much about your trip if he looks like he's getting annoyed by it. If you make ADRs, run it by him to make sure he's not against it, but otherwise, just keep him in mind with your plans. The DIS is here to share all your plans with, so you have US to talk to and be excited with. That's really what I learned from my planning.
If you need any more help, please just ask!
