I remember that feeling last year when I was staying on property for the first time and using
DDP. I started with a helpful site for deciding which parks to go to on which days (I use touringplans.com, but there are others). Once I knew that, I read and read and read and read on this board all about the restaurants. I also took into account my DD who was 5 at the time and what she would like to do. I only planned our TS meals and just decided on QS when we were at the parks based on where we were at the time when we got hungry. I didn't want to overwhelm myself with having to be at a certain place at a certain time more than once a day so we could just go with the flow and enjoy the World! Here is what we ended up with..
CRT for dinner at 8:10 p.m. (a truly magical experience- I thought it was too late of a reservation, but it was a pixie dust moment when we walked out of the castle just before Wishes started and found ourselves roped IN the castle area...not one person touching you...looking out on 1000's of people...looking up to see Tink fly right over your head...just magical!!)
Ohana breakfast....loved characters there and the food was great! Easy access from MK on boat or monorail. This was our slowest meal as it took a long time for the characters to come around to our table, but it was fine for our schedule that day)
Akershus for dinner...My DD is a huge princess fan so we had to do both princess meals.
CRT for breakfast....okay, I got a little carried away with the princess meals...she still loved it, but I wouldn't do it twice in one trip again....wasn't nearly as special the 2nd time in the same trip
50's Diner in HS....good home cooking meal (meatloaf, pot roast, that sort of thing)....fun, energetic place for my DD...loved it much more than Hollywood and Vine where we ate on a prior trip.
Crystal Palace...had to make the most of the DDP so we obviously did lots of character meals...loved the food and interaction with Pooh and Friends
Liberty Tree Tavern in MK...ate here bc it was the night before Thanksgiving and wanted a traditional meal...good food, don't think I would put on my "highly recommend" list if it wasn't Thanksgiving
Obviously, we made the most of our DDP! Loved all of our meals and would return to all of those places. This year we are going to do some again and try a few new ones (finally got a ressie for Chef Mickey, trying Garden Grill and Boma)
Good luck with your planning. My best advice is to just decide on some and go with it. As long as you read up on reviews, you should be able to pick many that you enjoy. One word of advice is to have your plan laid out with some backups listed as well. Get up in time to be online ready to go at the opening time (I believe it is 6 a.m. for online...account for your time zone) and make all of your ressies on that 180 day mark. Remember if you are staying at a resort that you can make up to 10 days of reservations on that 180 day mark. I didn't know that the first time we went and ended up getting up every day for a week to make my reservations. This year I knew to do all 8 days on the 180th day before our first day there. I got every ressie I wanted.
