We are WDW vets that also love DL. With all the changes in the past few years, WDW can be overwhelming for DLR people and for newbies, and for people dealing with the changes for the first time. First, where are you staying? That could influence some restaurant recommendations. For example, the Yachtsman Steakhouse at Yacht Club resort is terrific, but it would take park time to go there, but if you are staying at one of the resorts in walking distance and will be back at the resort some any way- it is a great choice. The first thing to realize is that unlike DLR where you can get anywhere in a short amount of time, WDW is huge and if you are park hopping or going to Disney Springs (DTD) or a resort for a meal, the transportation alone can take you an hour or more to get from point A to point B. You definitely want to think about distances when planning meals or hopping.
Next, you have stated that your must-dos include Victoria and Alberts and Be Our Guest. Unlike at DLR where dining reservations are generally easy to get, these are hard to get items. You want to be online when your dining opens up at 180 days, to try to get these 2 places. If it were me, if these 2 places are must dos, I would do that even though it means setting an alarm, getting up and booking them, and going back to bed. Our last trip, I booked right when the window opened up at 180 days and still could only get BOG dinner late in our trip (and unfortunately thanks to Hurricane Matthew, the park was closed that day so we didn't get our BOG dinner this trip). BOG dinner can be really hard to get. We enjoy it though and it is fun to meet the Beast. I think V&A is very hard to get too-- we have not done that one.
Character Breakfast--- with your time change, have you thought about a character lunch instead? WDW, the best times of day for shorter lines are around rope drop and late at night. For us, with just a one hour time change, pre park opening breakfasts have never worked for my morning adverse DD. If you do breakfast when the park opens, you lose a lot of time. We really enjoy doing lunch. That way we get some time in the park in the morning, and then take a nice TS break for lunch to recharge and gear up for more. We enjoy lunch at Tusker House at AK (Mickey, Daisy, Donald, Goofy) or at Crystal Palace (Pooh, Tigger, Piglet, Eeyore). At Tusker house, we have booked at 10:45 and then we get some of the breakfast buffet and often items start changing over to lunch. If you are going to do breakfast during park time, I would recommend Tusker House, because AK is typically pretty easy to do things even if you don't get an early start. MK that morning time means more. I will say though, that I think generally WDW is more crowded in the early hours than DL. We love how empty DL is the first couple of hours in the mornings-- I think it has to do with that local crowd. We don't get that feel at rope drop at WDW. The lines are shorter than they will be in the afternoon, but nothing like that early morning empty feel at DL.
As far as structuring your days, because of the ADR situation at WDW, the best thing to do is decide which parks you want to do which days before your ADR deadline. Then you plan your ADRs based on the park you are going to attend that day. On your water park day, you could plan a nice dinner at a resort or DS, since that won't interfere with theme park time. Allears.net has all the menus for all the restaurants. You definitely should plan a meal at World Showcase in EPCOT. When we go to DLR, EPCOT is the one thing we really miss. My family loves Biergarten. It is a German buffet in a restaurant with a great atmosphere and a German band that puts on shows throughout the day. It is a lot of fun. If you like Blue Bayou atmosphere- then the San Angel has that same type of atmosphere only with a Mexico flair (not at all the same type of food as Blue Bayou). Teppan Edo is fun if you like the Hibachi Grill experience (but it is pretty similar to the ones we have at home). There are other good restaurants throughout WS as well. You want to book dining reservations at that 180 day mark. You can always change things around later based on availability, but you want some ADRs in place at the outset. Assuming you are staying on property, then at 60 days out you want to book FPs. FP+ can be annoying and intimidating, but it is just something you have to deal with at WDW. Again, you want to book something, but you can always change it around later based on availability.
Have fun!!!
