I'm sure you know these tips already but:
Set up a Disney account if you haven't already and download the MyDisneyExperience app, from the app you can check wait times, change fastpass times, have a map etc.
Magic bands are love, magic bands are life. I thought magic bands were the most overhyped thing ever but after using one once I got an annual pass, it's the best thing ever. There's a bit of setup for all the functionalities of the band but once it's all set up, it's extremely convenient.
If you are staying at a Disney hotel you'll get a magic band as your hotel key and you can attach your ticket to the park, a credit card if you want as well (you will have to set up a PIN for it as a security measure), and a photopass (more on this later). If you do stay at a Disney hotel, be sure to customize the magic band online because if you do not you automatically get a grey one (if you wanted grey I guess it's not that big a deal).
If you don't stay at a Disney hotel and you still want to use a magic band (I HIGHLY RECOMMEND YOU DO), you can buy a cheap Magic Band 1 since the Magic Band 2's are rolling out, and attach it to your ticket and it'll have the same functionalities as the last tip minus the room key function. You can get a cheap magic band for ~$10 or less at any of the Disney outlets.
Once you guys finalize the dates you're going be sure to make your fast passes ASAP (especially for the newer rides like Seven Dwarves Mine Train, Frozen, Pandora). If you're staying at a Disney hotel you can make the passes 60 days in advance, if you're not at a Disney hotel you can make the reservations 30 days in advance. You can also make fast passes the day of through the MyDisneyExperience app and the fast passes are dynamic so if a particular time/ride is full, if someone drops their pass you can get that fastpass or swap your times etc.
HIGHLY RECOMMEND: You guys should split the cost of the photopass (Memory Maker $149) and have one account attached to it. You will be able to download all the pictures from rides, any photostop etc. It lasts for 30 days (so you have plenty of time), you must download the pictures within 45 days when it was taken. When Angie and I last went to Disney we stopped at every single photo opportunity and they just scan your magic band (or ticket) and the photos get uploaded to the MyDisneyExperience app within an hour and then you can save them. We went to Hollywood Studios which is one of the smaller parks and we had close to 50 pictures, the bigger parks there are tons more photostops and rides to get pictures on. So I'd imagine since you'd be there for 7 days you can have well over 100 pictures without trying, so your money will be well spent if you get the Memory Maker and use it.
If you or anyone you know has a costco/sam's club/BJ's membership, the Disney giftcards there are normally like $5-10 off of the whole price and you can use it at the parks so should buy some giftcards to use at the parks.
I'll add stuff as I think about it, but if you have any questions let me know. I live here in Orlando so I can give you tips/recommendations about the city, other parks and surrounding area as well. Have fun
P.S. I'm not sure how much you guys are getting the tickets for but depending on how many days you wants to go, the chances of a return trip within a year, and costs of memory maker and other costs, getting an annual pass may be cheaper.
I'm not sure how many days you're going but here are the prices for these:
The regular price of 4-day park hopper $425 + $149/2 (since only one of you needs it) memory maker.
6-day park hopper is $465 + $149/2 memory maker.
If you are a FL resident, you can get a gold annual pass which is $114 deposit + $40.12 a month/12 or $595 .
If you are not a FL resident, you can get a platinum pass (that's open to everyone), which is $779.
Both annual passes include memory maker, a magic band, 10-20% discounts, and free parking.
And if for some reason you guys want to come back within a year, you don't have to buy tickets again. Angie and I were doing calculations and if you go 5 times or more within a year of activation (not when you buy it, the first day you go to the park) it's already worth it and that's not including memory maker, discounts etc. And if you have extra time when you get to FL or have extra time during one of your days and want to go to the park for a few hours. You could always go, if you had a park hopper, it's limited to those days.
Or even one of you can get a platinum pass and it may be worth it just because of the discounts + memory maker.
There's a lot of different combinations you can do but I have a feeling atleast one annual pass or both of you getting annual passes could be worth it and a better bang for your buck. Of course all this info is contingent on whatever deals you can get and the likelihood of coming again within a year. Bottom line, if you have a chance of coming back within a year or going 6+ times during your trip, definitely worth the annual pass. If not, it still may be worth it.
